How to calculate the volume of walls. How to calculate cubic meters. How to calculate a cube of concrete for a tape base

Wood has always been the most popular material for building houses and baths. In our time, the demand for wood is still high. In order not to spend extra money, you need to correctly calculate how much timber is worth buying.

What are the difficulties in calculating the volume of a beam

At the time of preparation, before construction begins, it is not easy to calculate required amount timber. The volume is calculated in cubic meters, it is at this moment that difficulties begin. It is difficult for the buyer to understand the correct calculation of cubic capacity. It is required to calculate so that during the construction works I didn't have to buy extra lumber. After all, it will be a shame if in the midst of construction work there is not enough board. Again, you will have to run around the market or companies in search of the missing part, spend your money for delivery. Or after the construction is completed, you will have to think about where to attach the remaining material.

timber

If you figure it out, then there is nothing complicated about it. For example, take the following values.

When calculating, it turned out that 30 boards 6 meters long, 50 millimeters thick, 200 millimeters wide are required. All data must be multiplied. To do this, all units must be converted into one measurement value - a meter. It turns out that the width of the board is 0.20 meters, the thickness of the board is 0.05 meters. We multiply: width x length x thickness x quantity = 0.20 x 6 x 0.05 x 30 = 1.8 cubic meters.

If the buyer knows how many cubes of lumber are required, you can find out how many boards are contained in a cubic meter. We calculate how many pieces are in one cubic meter, if the lumber is 200 millimeters wide, 50 millimeters thick, and 6 meters long. All quantities must be divided. Volume/width/thickness/length=1/0.20/0.05/6=16.666.

For a quick calculation, you can use the table. Before you calculate the cubic capacity of the timber, you need to find out what parameters it will have.

Beam Width (mm)	Beam thickness (mm)	Beam length (m)	The number of cubic meters in one bar	The number of timber in one cubic meter (pcs)

According to the table, it is clear that in a cubic meter the number of units of timber depends on the dimensions of length, thickness, width. Therefore, in one cubic meter, changing the dimensions, we get a different amount of timber.

Subtleties in the calculation

In order to use your funds economically and rationally, it is necessary to calculate the number of cubic meters as accurately as possible. But when buying, take not much in stock, about five to ten percent more, because the timber may turn out to be defective, it may twist at the time of work, and other unforeseen situations may also occur.

Whatever the volume of work, you always need to take different ones. For the construction of walls, only one is suitable, on truss system different ones are used. Therefore, it is necessary to carefully plan the project of a house or a bath. Using tables or formulas, calculate the quantity and required dimensions.

How to independently calculate the cubic capacity of a bar for a house

For example, consider the option of a small country house one-story house for summer living. It was decided to build a house six by six meters with a ceiling height of three meters and make one six-meter partition. We calculate the cubic capacity of the timber per house with such parameters. If the house will be used only during the summer period, it is worth buying a bar with a section of 100 x 100 millimeters. When planning year-round living, it is necessary to make walls of thicker material, the width of which will be at least 150 millimeters.

Calculation of the required volume of timber per house:

perimeter: (length + width) x 2 + partition = (6 + 6) x 2 + 6 = 30 meters;
house wall volume: (perimeter x beam thickness x wall height) = 30 x 0.1 x 3 = 9 cubic meters for summer house. Or 30 x 0.15 x 3 = 13.5 cubic meters for a house with winter residence;
gables: (width x beam thickness x height) \u003d 6 x 0.1 x 3 \u003d 1.8 cubes will be required for a summer house. And 6 x 3 x 0.15 = 2.7 cubic meters for living in the house all year round.
Add up the results and add 20% of the total volume to them, for a reserve. (9 + 1.8) + 20% = 10.8 + 2.16 = 12.92 cubic meters and (13.5 + 2.7) + 20% = 16.2 + 3.24 = 19.44 meters cubic.

How to calculate the cubic capacity of a beam per bath

Recently, the fashion for a holiday outside the city has returned. Young families with children are increasingly purchasing garden plots. Many are wondering how to build with their own hands and how to calculate the amount of lumber per bath. If you understand all the subtleties and moments, then there is nothing complicated.

The most demanded 4 x 6 meters. It is better to do it from natural timber. Starting construction, you need to decide on the exact amount of lumber. For external walls use 250 x 130 mm, for internal partitions 130 x 95 mm. Let's calculate:

The perimeter of a bath of this size is 5500 x 3500 millimeters.
For each of the walls, 21 timber is required. This is calculated taking into account the size of the floor and the thickness of the ceiling.
The log house has four walls. It turns out (6 x 2) + (4 x 2) = 20 meters. Converting to millimeters, it turns out 20000.
We need to find the total length of the bars. For this, the number of bars x per length = 21 x 20000 = 420 meters. Converting to millimeters, it turns out 420000.
Multiplying the resulting amount by the size of the beam, we get 420 x 250 x 130 = 13.65 cubic meters.

To calculate the required amount of timber for partitions, use the same description with the only difference that a different size of timber is required, 95 x 130 millimeters in size. The cubic capacity for partitions is also calculated. For internal walls a smaller timber is used in thickness.

For large volumes

How to calculate the cubic capacity of a bar for big house? In this case, lumber of different lengths, widths, thicknesses will be required. It will be easier to calculate not the volume of wood (dense), but use the calculation of the "folded cubic meter". In the first case, the results are used when measuring each beam separately, without voids. In the second case, all the lumber is stacked, joining the bars together. different size so that they are the same length. When everything is sorted and evenly stacked, measure the dimensions (width, length, height). The results obtained are multiplied. Now - how to find out the cubic capacity of a dense beam. To do this, the result of the folding cubature should be multiplied by a special coefficient.

Crown calculation

In order to find out the required number of crowns in a log house, it is necessary to divide the height of the house by the height of the timber (working). Let's calculate the cubature of a bar for a house measuring 9 x 9 meters with one cut. For example, we use a beam profiled 140 x 190 millimeters, it is necessary to calculate the number of crowns at a height of 2.5 meters.

Calculation: 2500/130 = 19.23. We round up, it turns out 19 crowns are needed for a given height. The length of one crown is 9 meters, it is required to calculate how many running meters are in one crown, along with overcuts. Let's calculate how many linear meters in the lower crown. To do this, add up all sides 9 + 9 + 9 + 9 + 9 = 45 meters. To calculate the total running meters in this house, it is necessary to multiply the length of one crown by the number of crowns. It turns out, 19 x 45 = 855 running meters. Given the zero crown, you need to add it to the total number so that there is a row shift. 2.5 x 9 \u003d 22.5 meters of running halves of the crown. 855 + 22.5 = 877.5 m. p., this is with door and window openings.

How to correctly calculate the cubic capacity of a profiled beam? To do this, multiply the resulting length of the crowns by the height of the timber and multiply by the thickness of the profiled timber = 877.5 x 140 x 190 = 23.34 cubic meters will be required for a house measuring 9 x 9 meters. Be sure to take into account when calculating the loss of the beam, approximately 7% of the total, for trimming and sawing.

Advantages of a wooden house built using timber

No need for internal and exterior finish at home. The walls are even and smooth. They look beautiful.
Moisture does not penetrate into the seams located between the crowns. Moisture does not collect on the walls and rot does not appear.
After a while, after shrinkage of the log house, no caulking is required.
The beam has a tight connection with a lock, which protects against blowing.
Virtually no cracks appear and are not deformed during shrinkage.
Natural material, environmentally friendly.
It does not require long assembly, it is assembled quickly, like a designer.
The houses have a beautiful aesthetic appearance.
The house is easy to care for, there is practically no dust on the walls.
Possibility to paint the house in any color.

Instruction

To calculate the cubic capacity of a room, multiply its length,. That is, use the formula:
K = L x W x H, where:
K - cubic capacity of the room (volume expressed in cubic meters),

L, W and H - length, width and space, expressed in meters, respectively.
For example, if the length of the room is 11 meters, the width is 5 meters, and the height is , then its cubic capacity will be 11 x 5 x 2 = 110 cubic meters.

If one or more characteristics of the room are unknown, then measure them using construction tape measure or electronic rangefinder. When using an electronic rangefinder, make sure that it is directed strictly perpendicular to the wall, the distance to which is . To improve the accuracy of the calculations, measure the height and width twice - at opposite walls, and then find the arithmetic mean (add and divide by 2).

Let, for example, measurements of the length of the room show 10.01 m and 10.03 m, measurements of the width - 5.25 m and 5.26 m, and measurement of the height - 2.50 m. In this case, the cubic capacity of the room will be equal to:

(10.01 + 10.03) / 2 x (5.25 + 5.26) / 2 x 2.5 \u003d 131.638

(in most cases, three decimal places is enough).

If you know the area of \u200b\u200bthe room, then to calculate the cubature, simply multiply this area by the height. That is, use the formula:
K \u003d P x B, where
P is the area of the room, given in square meters (m²).
So, for example, if the area of the room is 100 square meters, and its height is 3 meters, then its volume will be:

100x3=300 (cubic meters).

If the room has complex shape, then to determine its area, use the appropriate geometric formulas or divide the room into simpler sections.
So, for example, the circus arena always has the shape of a circle with a radius of 13 meters. Therefore, its area will be equal to πR² = 3.14 x 169 = 531 (square meter).
If, for example, the room consists of three rooms with an area of 30, 20 and 50 m², then the total area of \u200b\u200bthe room will be 100 m².

If on a plane a square can be compared in terms of primitiveness only with an equilateral triangle, then four more regular polyhedra compete with a cube. However, it is very simple, maybe even simpler than a tetrahedron.

Instruction

What is a cube? Otherwise, this shape is called a hexahedron. This is the simplest of the prisms, its sides are in pairs, like any of the prisms, and. You may also find that the hexahedron is called a parallelepiped. And there is. A cube is a rectangular parallelepiped with equal edges, each of whose six faces is a square. At each vertex of the cube, three of its edges converge, so in total it has six faces, eight and twelve edges, the adjoining faces are perpendicular to each other, that is, they create angles of 90 °.

If you do not have any data about the cube at the beginning of the calculations, do it simply. Name the edge of the cube a. Now you will start from this very non-numerical value in the calculations.

If one of the edges of the cube is a, then any other edge of the cube is equal to a. The area of the face of a cube is always a^2. The diagonal of the face of a cube is calculated by the Pythagorean theorem and is equal to a times the root of two. All of the above follows from the fact that each face of a cube is a square, which means that the edge of the cube is in each case the side of the square, and the face of the cube is equal to the area of the square with side a.

We now turn to formulas of the next order. Knowing one face of a cube, it is easy to find out the area of its surface, it is 6a^2. The volume of a cube is a^3, since the area of any straight prism is equal to the product of the length of the prism times its width times its height, and in our case all these parameters are equal to a.

The length of the diagonal of a cube is equal to a times the root of 3. This is clear from the theorem that in any rectangular parallelepiped, the square of the diagonal is equal to the sum of the squares of the three linear dimensions of a given polyhedron. At the intersection of the diagonals of a cube, or other parallelepiped, there is a point of symmetry. This point divides the diagonals equally, in addition, nine planes of symmetry pass through the point of symmetry in the cube, dividing the cube into equal parts.
So you have learned all the information necessary and sufficient to calculate any cube parameter. Try.

If there are no problems with the determination of weight and volume, for example, when buying liquids or bulk materials, then with timber the situation is different. Here, the system for determining the volume of the required amount of this raw material raises many questions, since no one wants to pay extra money.

Instruction

It turns out that not all buyers realize how many species actually exist. But it differs from each other in the degree of processing, type, grade, which directly affects it. This is how the slab is calculated - a very popular type of lumber.

First, the measured batch of business slab should be sorted into. One group consists of boards with a length of more than 2 m, the other - less than 2 m. Stacking is carried out with thick and thin ends alternately in different directions, while the surface of the slab remains at the top and bottom. The stack should be compact and tightly stacked at right angles and have the same height.

The volume of sawn timber from softwood and hardwood can be determined in two ways.

The first method involves measuring each bar or board, and then the volume, after which the results are summarized.

The second way is with the help of a cube, a special table designed to determine the volume of such lumber. The measurement of boards related to unedged lumber is performed somewhat differently. In this case, the width of one-sided edged and unedged board calculated as half the sum of the upper and lower planes.

Of course, it is worth dwelling separately on the measurement of cubature roundwood. Here you have to measure each log separately - the length and width of the upper and lower ends. The special tables on which these calculations are made are called, which were discussed above.

After the volume of each log is measured separately, addition is made and the total cubic capacity is obtained. There is already a corresponding computer program.

What methods can calculate the volume of concrete

The execution of construction work is preceded by the development of the project. At this stage, the type of foundation base is determined, and the volume of concrete solution required for the construction of the base is calculated. On the design stage the need for a solution for pouring monolithic walls and a concrete floor is calculated. Definition of cubature concrete mix required to perform the work, is made according to the volume of the concreted structures of the building.

Various methods are used to perform calculations.:

manual. It is based on the calculation of the volumes of the foundation, main walls and floor. The calculation is made on a conventional calculator according to school formulas for calculating volume and does not take into account the concrete shrinkage coefficient. The value obtained differs slightly from the results of calculations using software tools;
program. The initial data entered into the program about the type of foundation, its dimensions, design features and brand of concrete are promptly processed. As a result, a fairly accurate result is produced, which you can focus on when purchasing building materials for building a foundation base, building walls or pouring a floor.

Features when calculating the volume of concrete

For getting exact result not enough to take into account inner size formwork. The second method is more accurate, since the online calculator takes into account all the data: the type of foundation, the section of the foundation base, the presence of a reinforcing cage and the grade of mortar.

Getting ready to determine the volume of concrete - how to calculate without errors

When preparing to perform calculations, it should be remembered that the need for a concrete mixture is determined in cubic meters, and not in kilograms, tons or liters. As a result of manual or software calculations, the volume of the binder solution will be determined, and not its mass. One of the main mistakes that novice developers make is to perform calculations before the type of foundation is determined.

The decision on the design of the foundation is made after the following works have been completed:

the production of geodetic measures to determine the properties of the soil, the level of freezing and the location of aquifers;
calculation of the load capacity of the base. It is determined based on the weight design features structures and natural factors.

How to calculate the amount (volume) of concrete mix

type of foundation being built;
foundation dimensions, its configuration;
brand of mixture used for concreting;
soil freezing depth.

The accuracy with which the volume of concrete is calculated depends on the data used for the calculation.

They are different for each type of foundation.:

when calculating the tape base, its dimensions and shape are taken into account;
for columnar base it is important to know the number of concrete columns and their dimensions;
calculate the cube of concrete for solid plate possible according to its thickness and dimensions.

The accuracy of the result obtained depends on the completeness of the data used for the calculation.

How to calculate concrete in cubes for a foundation

For all types of foundations, the need for concrete is determined by a formula that takes into account the total volume of foundation structures being erected. In this case, the part of the foundation poured into the ground is also taken into account without fail. To perform calculations, one should be guided by the dimensions indicated in the project documentation.

columnar;
grillage.

Determining the need for concrete mortar for each type of foundation has its own characteristics.

How to calculate a cube of concrete for a tape base

strip foundation calculator

Base belt type quite popular. It is used for the construction of private houses, outbuildings and country houses. The structure is a solid concrete strip reinforced with steel bars. Monolithic tape follows the contour of the building, including internal partitions.

Table of composition and proportions of concrete mix

The calculation of the volume of concrete for a monolithic strip foundation is carried out using a simple formula V = AxBxP. Let's decrypt it:

V - the need for a concrete solution, expressed in cubic meters;
A is the thickness of the foundation tape;
B - height of the tape base, including the underground part;
P is the perimeter of the formed tape contour.

Multiplying these parameters together, we calculate the total cubic capacity of the concrete solution.

Consider the calculation algorithm for a strip base with dimensions of 6x8 m, a thickness of 0.5 m and a height of 1.2 m. Perform the calculation according to the following algorithm:

Calculate the perimeter by doubling the length of the sides 2x(6+8)=28m.
Calculate the cross-sectional area by multiplying the thickness and height of the tape 0.5x1.2 \u003d 0.6 m 2.
Determine the volume by multiplying the perimeter by the cross-sectional area 28x0.6 \u003d 16.8 m 3.

The result obtained has a small error associated with the fact that it is not taken into account reinforced concrete reinforcement and shrinkage of the mixture during vibratory compaction.

Strip foundation scheme

How to calculate a cube of concrete for a pile type foundation

The base in the form of concrete columns is one of the simplest. It represents reinforced concrete supports, evenly spaced along the contour of the building, including at the corners of the building, as well as at the intersection of internal partitions with walls. Part of the support elements is located in the ground and transfers the load from the mass of the structure to the soil. The calculation algorithm provides for the determination of the total need for concrete by multiplying the volume individual columns for their number.

For calculations, use the formula - V \u003d Sxn, which is deciphered as follows:

V is the amount of solution for pouring columns;
S is the cross-sectional area of the support element;
n is the total number of pile columns.

Using the example of the requirements of a project involving the installation of 40 piles with a diameter of 0.3 m and a total length of 1.8 m, we calculate the required amount of concrete:

Calculate the area of the pile by multiplying the coefficient 3.14 by the square of the radius - 3.14x0.15x0.15 \u003d 0.07065 m 2.
Calculate the volume of one support by multiplying its area by the length - 0.07065x1.8 \u003d 0.127 m 3.
Determine the required amount of the mixture by multiplying the volume of one pile by the total number of supports 0.127x40 \u003d 5.08 m 3.

How to calculate the cube of concrete

With a rectangular section of the supporting columns, to calculate the cross section, it is necessary to multiply the width and thickness of the element.

How to calculate concrete for a column base with a reinforced concrete grillage

To improve the strength characteristics of the columnar base, the protruding parts of the supports are combined with a reinforced concrete structure, which is called a grillage. It is made in the form of a solid reinforced concrete tape or slab, in which the column heads are concreted.

How to calculate the volume of concrete for the construction of a strip foundation and piles

Determine the cross-sectional area of the grillage by multiplying its thickness by the height;
Calculate the volume of the grillage by multiplying the cross-sectional area by the length of the structure.

The obtained value corresponds to the need for a concrete mixture for concreting the grillage base.

We calculate the volume of concrete for the foundation in the form of a solid slab

The slab type base is used on difficult soils with a high moisture concentration. Buildings are erected on it basement. This design allows you to evenly distribute the load from the mass of the structure on the soil and provide increased rigidity and stability of the object under construction. The use of reinforcement allows you to increase strength slab foundation. The design is reinforced concrete slab in the form of a rectangular parallelepiped.

How to calculate the volume of concrete

Explanation of designations:

V - volume concrete composition for pouring the slab;
S is the area of the slab base in cross section;
L is the length of the foundation structure.

For a foundation 12 m long, 10 m wide and 0.5 m thick, consider the calculation algorithm:

Determine the area by multiplying the width of the slab by its thickness 10x0.5 \u003d 5 m 2.
Calculate the volume of the base by multiplying the length of the structure by the area 12x5 \u003d 60 m 3.

The resulting value corresponds to the need for concrete mix. If the slab foundation has a complex configuration, then it should be divided on the plan into simpler figures, and then the area and volume should be calculated for each.

How to correctly calculate the cube of concrete for the construction of walls

Calculator for calculating the amount of concrete for a strip foundation on the site

For the construction of massive buildings, strong boxes are constructed from concrete reinforced steel reinforcement. To determine the need for building materials, builders face the task of calculating the volume of concrete for such structures. To perform calculations, use the following formula - V \u003d (S-S1) x H.

Let us decipher the notation included in the formula:

V - the amount of concrete mix for building walls;
S is the total area of the wall surface;
S1 - total area of window and door openings;
H is the height of the concreted wall box.

When performing calculations, the total area of the openings is determined by summing up the individual openings. The calculation algorithm is reminiscent of determining the need for concrete for a slab base and can easily be done independently using a calculator.

How to calculate a cube of concrete for pouring a floor

How to calculate the volume of concrete for the floor

To increase the load capacity of the floor and ensure its flatness, a concrete screed is performed. After the concrete has hardened, such a surface serves as the basis for laying floor coverings or ceramic tiles. To prevent cracking, the thickness of the molded concrete screed is 5–10 cm. This is due to the fact that more thin material cracked during use. It is important to correctly calculate the cube of concrete so that the formed screed is strong and has the thickness provided for by the project.

The formula for determining the amount of solution V \u003d Sxh is easily deciphered:

V is the amount of poured material;
S is the total area of the concreted screed;
h is the thickness of the concrete base.

Let's figure out how to perform calculations for a room with dimensions of 6x8 m and a concrete base thickness of 0.06 m:

Determine the area floor surface, multiplying the length and width of the room - 6x8 \u003d 48 m 2.
Calculate the volume of poured concrete composition to form a screed by multiplying the area by the layer thickness - 48x0.06 = 2.88 m 3.

Guided by the above algorithm, you can easily determine the amount of concrete composition for concreting the floor. There are situations when the rough surface has a slope. In this case, the formed screed has different thickness by area of the room. In this situation, you can use the average layer thickness, which reduces the accuracy of the calculations.

Conclusion - why you need to know how to calculate a cube of concrete

Being engaged in construction and planning to manufacture independently concrete mortar or purchase it from enterprises reinforced concrete products in the required quantity, it is important to know how to calculate the volume of concrete. This will allow you to predict the amount of upcoming expenses, purchase building materials in a timely manner, and complete the work on schedule. You can make calculations both manually on a calculator and using software tools. The main thing is to master the calculation methodology and use reliable data to determine the amount of concrete.

Volume is a quantitative characteristic of the space occupied by a body, structure or substance.

Volume calculation formula:

V=A*B*C

A - length;
B - width;
C is the height.

You can quickly perform this simple mathematical operation using our online programs. To do this, enter the initial value in the appropriate field and click the button.

Converting square meters to cubic

Most often, such a conversion is useful when calculating the amount of building materials, since some of them are sold in cubic meters, and are intended for arranging various surfaces that are conveniently measured in square meters. In order to convert square meters to cubic meters, in addition to the length and width of the product, you need to know its thickness. Product volume is calculated by the formula V=a*b*c, where

a,b and c - length, width and height in meters.

For example, you need to sheathe a room with clapboard.

How to calculate the volume in m3?

The total area of the walls is 200 square meters. The lining is sold in cubic meters. The lining thickness is 1 cm. In order to calculate the volume of building materials, the following calculations must be made:

Now you need to multiply the area of \u200b\u200bthe walls by the thickness of the lining in meters: 200 * 0.01 \u003d 2 cubic meters.

Thus, in order to sheathe 200 meters square walls you will need 2 meters of cubic lining.

Convert cubic meters to square meters

In some cases, it may be necessary to convert cubic meters to square meters - that is, to measure how many square meters of material are contained in one cubic meter. To do this, you need to know the volume and thickness (height) of the material and make calculations using the formula: S = V / a, where:

S - area in square meters;
V - volume in cubic meters;
a - thickness (height) of the material.

Thus, if you need to determine what area can be sheathed with 1 cubic meter of lining 1 cm thick, you need:

Convert the thickness of the lining in centimeters to meters: 1/100 \u003d 0.01 meters;
Divide the volume of lining in cubic meters by the resulting thickness in meters: 1 m3 / 0.01m = 100 m2.

Thus, with a clapboard, the volume of which is 1 cubic meter, it is possible to sheathe walls with an area of 100 square meters.

In order for these calculations not to seem so complicated, it is enough to visualize the concepts of a cubic meter and a square meter. So to imagine 1 cubic meter, you need to mentally draw a cube, the sides of which are equal to 1 meter.

To imagine how many square meters are contained in one cubic, you can divide the vertical plane of the cube into conditional strips, the width of which is equal to the thickness of the material being represented. The number of such bands will be equal to the area of the material.

How to find volume in terms of area

Volume - a measure of capacity, expressed for geometric shapes in the form of the formula V=l*b*h. Where l is the length, b is the width, h is the height of the object. In the presence of only one or two characteristics, it is impossible to calculate the volume in most cases. However, under certain conditions it seems possible to do this through the area.

Instruction

Task one: calculate the volume, knowing the height and area. This is the easiest task, because
Calculation of heating by room volume calculator

area (S) is the product of length and width (S= l*b), and volume is the product of length, width and height. Substitute the area in the formula for calculating the volume instead of l * b. You will get the expression V \u003d S * h. Example: The area of \u200b\u200bone of the sides of the parallelepiped is 36 cm², the height is 10 cm. Find the volume of the parallelepiped. V = 36 cm² * 10 cm = 360 cm³. Answer: The volume of the parallelepiped is 360 cm³.
Task two: calculate the volume, knowing only the area. This is possible if you calculate the volume of a cube by knowing the area of one of its faces. Because the edges of the cube are equal, then extracting from the area value Square root, you get the length of one edge. This length will be both the height and the width. Example: the area of one face of a cube is 36 cm². Calculate the volume. Take the square root of 36 cm². You got a length of 6 cm. For a cube, the formula will look like: V \u003d a³, where a is the edge of the cube. Or V \u003d S * a, where S is the area of one side, and is the edge (height) of the cube. V \u003d 36 cm² * 6 cm \u003d 216 cm³. Or V \u003d 6³cm \u003d 216 cm³. Answer: The volume of the cube is 216 cm³.
Task three: calculate the volume if the area and some other conditions are known. The conditions may be different, in addition to the area, other parameters may be known. The length or width can be equal to the height, more or less than the height several times. Additional figures may also be given to help with volume calculations. Example 1: Find the volume of a prism if you know that the area of one side is 60 cm², the length is 10 cm, and the height is equal to the width. S = l * b; l=S:b
l \u003d 60 cm²: 10 cm \u003d 6 cm - the width of the prism. Because width equals height, calculate the volume:
V=l*b*h
V \u003d 10 cm * 6 cm * 6 cm \u003d 360 cm³ Answer: the volume of the prism is 360 cm³
Example 2: find the volume of the figure, if the area is 28 cm², the length of the figure is 7 cm. Additional condition: the four sides are equal to each other and connected to each other in width. To solve, you should build a parallelepiped. l=S:b
l \u003d 28 cm²: 7 cm \u003d 4 cm - width Each side is a rectangle, the length of which is 7 cm and the width is 4 cm. If four such rectangles are connected together in width, then a parallelepiped will be obtained. The length and width in it are 7 cm each, and the height is 4 cm. V \u003d 7 cm * 7 cm * 4 cm \u003d 196 cm³ Answer: The volume of the parallelepiped \u003d 196 cm³.

Volume is a geometric term that allows you to measure the quantitative characteristics of residential and non-residential space.

It is possible to determine the volume of a room, having information about its linear dimensions and shape characteristics. Volume is very closely intertwined with capacity characteristics. Surely everyone is familiar with such terms as the internal volume of a vessel or any container.

The volume unit is classified according to worldwide standards. There is a special measurement system - SI, according to which a cubic meter, liter or centimeter is a metric unit of volume.

Any room, whether it is a living room or a production room, has its own volume characteristics. If we consider any room in terms of geometry, then the room is comparable to a parallelepiped. This is a hexagonal figure, in the case of a room, its edges are the walls, floor and ceiling. Each side of the room is a rectangle. As is known from geometry, there is a formula for finding the volume of a rectangular parallelepiped. The volume of this figure is calculated by multiplying the three main dimensions of the parallelepiped - the length, width and height of the faces. You can also calculate the volume of a room using a simpler formula - the floor area is multiplied by the height of the room.

How to find out the volume of a room

So, how do you calculate the volume of a particular room? First, we measure the length of the wall, the longest in the room. Then we determine the length of the shortest wall in the room. All these measurements are carried out at the floor level, along the line of the baseboards. When measuring, the tape measure must be level. The time has come to measure the height of the ceiling. To do this, you need to hold a tape measure from floor to ceiling in one of the corners of the room.

All measurements must be recorded to the nearest tenth. After that, you can proceed directly to the calculation of the volume of the room. We take the length big wall, multiply it by the length of the smallest wall, then multiply the result by the height of the room. As a result, we get the necessary numbers - the volume of the room.

It may be necessary to calculate the volume of a room in the most different situations. So, you need to know the volume of the room when installing a sectional heating radiator. The number of sections in it directly depends on the volume of the room. If you are installing an air conditioner, you also need to know the volumes of the room, since a separate air conditioner is only designed for a specific volume of the room.

Complex room volume

In the case when the room has an irregular shape, you need to start again from the figure of a parallelepiped. In this case, the room will be represented by a large and small volumetric body. So, the volume must be measured separately for a large parallelepiped, and then for a small one. After that, the two volumes are added together. It happens that the structure of the room is completely non-standard, there may be arches and niches of a semicircular formation. In this case, the volumes must be calculated using a different formula - the volume of the cylinder. The volume of a cylinder is always calculated according to a single formula - the area of \u200b\u200bits base is multiplied by the height of a cylindrical body. Semicircular structures in the room can be represented as part of a cylinder, based on this, calculations are made of the total volume of the cylinder, and then the excess part is subtracted from them, in accordance with the dimensions of the semicircular niche.

How to find the volume of a room

An assessment of the volume of premises is quite often required in the production of construction and repair work. In most cases, this is required to clarify the amount of materials needed for repairs, as well as for the selection effective system heating or air conditioning. Quantitative characteristics describing space, as a rule, require some measurements and simple calculations.

2. If the room has an irregular or complex shape, the task becomes a little more complicated. Break the area of the room into several simple figures and calculate the area of \u200b\u200beach of them, having previously made measurements. Add up the resulting values, summing the area. Multiply the amount by the height of the room. Measurements must be carried out in the same units, for example, in meters.

5. Separately calculate the volumes of verandas, bay windows, vestibules and other auxiliary elements of the structure. Include this data in the total volume of all rooms in the building. Thus, you can easily find the volume of any room or building, the calculations are quite simple, try and be careful.

Room volume formula

How to calculate the volume of a room

Volume is a quantitative feature of a place. The volume of the room is determined by its shape and linear dimensions. The concept of capacity is closely intertwined with the concept of volume, in other words, volume interior space vessel, packing box, etc. Accepted units of measurement - in the SI measurement system and its derivatives - cubic meter m3, cubic centimeter, liter. You will need To measure the volume of a room, you will need a tape measure, a sheet of paper, a calculator, a pen. 1 Each room, for example a room, is, from a geometric point of view, a rectangular parallelepiped.

A parallelepiped is a large figure with 6 faces. and it doesn't matter which of them is a rectangle. The formula for finding the volume of a rectangular parallelepiped is: V=abc. The number of a rectangular parallelepiped is equal to the product of 3 of its dimensions. Apart from this formula, you can measure the amount of space by multiplying the floor area by the height.

2 So start calculating the volume of the room. Determine the length of one wall, later determine the length of the 2nd wall. Take measurements on the floor, at the level of the plinth. Keep the tape measure straight.

At the moment, determine the height of the room, to do this, go to one of its corners, and accurately measure the height along the corner from floor to ceiling. Write down the acquired data on a piece of paper so as not to forget.

How to calculate the volume in m3 of concrete calculator

At the moment, proceed to the calculations: multiply the length of a long wall by the length of a short wall, multiply the acquired product by the height and you will get the required result.

The volumes of the premises are calculated in various occasions: 1) in the case of purchasing an air conditioner, since air conditioners are designed for a certain number of rooms; 2) in the case of installing heating radiators in rooms, since the number of sections in the radiator depends on the volume of the room. 3 If you have an irregularly shaped room, in other words, it consists of a seemingly huge parallelepiped and a small one. In this case, it is necessary to measure the number of each of them separately, and then add them up. If your room has an alcove. then its amount must be calculated using the formula for the volume of a cylinder. The number of any cylinder is equal to the product of the area of the base and the height: V \u003d? r2 h, where. is the number "pi" equal to 3.14, r2 is the square of the radius of the cylinder, h is the height.

Imagine your alcove for yourself as part of a cylinder, calculate the amount of what seems to be the entire cylinder, later look at what part of this cylinder your alcove occupies, subtract the excess part from the total volume.

How to calculate the area of a room?

If a room has four walls and has a standard geometric figure with right angles, then it is necessary to measure two walls and multiplying the obtained two numbers by each other we get the area of the room, and for the volume you need to multiply the result by the height. but this is only with regular geometric shapes.

It is more difficult to find the area and dimensions when the shape of the room is the wrong size, for example.

Then you need to apply all the knowledge of geometry, namely, divide the room into several regular figures and, in accordance with the formulas of these figures, find their area, and then add all the results together, then you get the total area of \u200b\u200bthe room. To find the height, you need to multiply the result of the total area by the height.

Things are even worse with non-standard premises with irregular wall and roof angles. Then you have to transfer all the dimensions of the room to paper, divide it into regular figures and, based on each figure, find its area and volume, and then summarize the results.

The area of the room does not include protrusions of windows and other things that are higher than the floor, but they are included in the calculation of the volume of the room.

How to calculate the area of a room

In case of room measurement irregular shape for a more accurate calculation of the area, it is recommended to divide it into rectangles. By calculating the area of each such plot, you can find out total area rooms by simply summing up all the results obtained.

If it is not possible to divide the room into rectangular sections, then you can try such shapes as a triangle or a sector of a circle. The area of a triangle is calculated using Heron's formula: S=v**).

P - half-perimeter of a triangle, which can be calculated in this way: p \u003d / 2

Estimation of the volume of premises is quite often required in the production of construction and repair work. In most cases, this is required to clarify the amount of materials needed for repairs, as well as to select an effective heating or air conditioning system.

Quantitative characteristics describing space, as a rule, require some measurements and simple calculations.

1. The simplest case is when you want to determine the volume of a room with a regular rectangular or square shape. Using a tape measure, measure in meters the length and width of the walls, as well as the height of the room. It is most convenient to take measurements along the floor, along the baseboards. Multiply the obtained indicators of length, width, height and you will get the desired volume.

2. If the room has an irregular or complex shape, the task becomes a little more complicated. Break the area of the room into several simple shapes (rectangles, squares, semicircles, and so on) and calculate the area of \u200b\u200beach of them, having previously made measurements. Add up the resulting values, summing the area. Multiply the amount by the height of the room. Measurements must be carried out in the same units, for example, in meters.

3. When carrying out construction work, the determination of the volume of the entire structure is determined by the standards. The so-called building volume of the ground part of the building with an attic can be calculated by multiplying the horizontal sectional area along the outer contours at the level of the lower floor. Measure full height buildings from the level of the finished floor to the top of the attic floor insulation. Multiply both numbers.

4. If there are floors of different sizes, determine the total volume of premises in the building by adding the volumes of all parts. In the same way, the volume is determined if the premises have different outlines and designs.

5. Separately calculate the volumes of verandas, bay windows, vestibules and other auxiliary elements of the structure (with the exception of covered and open balconies). Include this data in the total volume of all rooms in the building. Thus, you can easily find the volume of any room or building, the calculations are quite simple, try and be careful.

2.4 Capacity calculation public buildings and the size of their land

Public buildings house institutions and public service enterprises.

By specialization and types of services, public institutions and enterprises are divided into preschool (nurseries and kindergartens), schools, health care, cultural and educational, public utilities, trade and distribution, public catering, administrative and economic, etc.

Calculation of the volume of the room.

The composition of public institutions for each inhabited place initially developed in the draft district planning, which presents the entire system of resettlement in the area and the placement of institutions and service enterprises in settlements. These developments are taken into account when determining the composition of public buildings in a particular populated area. This takes into account the possibility of further operation of existing buildings.

Capacity calculation or bandwidth institutions and service enterprises is produced according to the settlement norms (SNiP).

2.5 Drawing up a list of design buildings and structures

Public buildings house institutions and public service enterprises. By specialization and types of services, public institutions and enterprises are divided into:

Preschool children's (nurseries and kindergartens);

school;

healthcare,

cultural and educational;

· household;

· trade and distribution;

· Catering;

Administrative and economic and others.

According to the territorial coverage of services, they can be divided into the following groups:

1) servicing residents of several settlements;

2) services for residents of one populated area;

3) services for residents of certain parts of a populated area.

The first group includes institutions located in regional centers and serving the entire population of the region (district Council of People's Deputies, House of Culture, post office, department store, etc.), as well as institutions serving a group of settlements and located in the largest of them, for example , in the central estates of farms (the village Council of People's Deputies, the office of the state farm, the board of the collective farm, secondary school, hospital, etc.). The second group consists of institutions serving all residents of one populated area. The third group includes institutions that serve residents of certain parts of a large populated area and are represented in it by several buildings located at different points (kindergartens and nurseries, schools, grocery stores, etc.).

This system of service establishments was called the "step system". It ensures the proximity of service establishments to residents. Thus, the first group includes institutions of episodic use, the second - periodic use, and the third - provides for daily maintenance.

The composition of public institutions for each populated area is initially developed in the draft district planning, which presents the entire system of resettlement in the area and the placement of institutions and service enterprises in settlements. These developments are taken into account when determining the composition of public buildings in a particular populated area. At the same time, the possibilities of further operation of existing public buildings are taken into account.

The calculation of the capacity or throughput of institutions and service enterprises is carried out according to the calculated norms.

In accordance with the calculated data of public institutions, standard designs of public buildings are selected for a particular populated area. At the same time, it is advisable to give preference to such standard projects, which provide for the placement of several public institutions in one building. At the same time, the construction and operating cost per unit volume of the building is reduced, its appearance becomes more interesting, and the architecture of the public center where the building is located is enriched.

We should start with the fact that all the units of measurement used in modern physical science and in everyday life are nothing but the result of the painstaking work of scientists over hundreds of years. In order to bring all inches, miles and pounds to a common denominator, we decided to switch to a common unit of measure. The modern metric system was based on kilograms and meters. All other units of measurement are derivatives, including the cubic meter. This article will tell you how to calculate the cubic capacity of various building materials.

A cubic meter is a measure of the volume of a body or substance. A cubic meter is the volume of a cuboid figure with edges exactly one meter long. The formula for calculating a cubic meter is very simple and looks like this: 1m3 = 1mx1mx1m.

Measured in cubic meters are subject to both solid substances (for example, lumber, reinforced concrete blocks) and liquid(dwelling water consumption, concrete consumption), and gaseous(measurement domestic gas for utility bills).

Obviously, if the source information is presented in related units of measurement (for example, in liters or cubic centimeters), then their conversion to volume units will not take much time. However, if mass or area is to be converted, some Additional Information, and the calculation is more difficult.

Calculation of the cubic capacity of edged lumber:

When calculating the cubature of an edged board, you will need to apply the knowledge acquired in geometry lessons. In the case of edged lumber, you simply need to multiply the three standard values. However, an incomplete pack of boards (beams) is taken into account. It is necessary to calculate the cubic capacity of one element first, then, having counted the total number of boards (bars) in a pack, multiply this number by the resulting volume value.

When calculating the cubature in this case need to work with the same units of measurement, i.e. convert all board sizes to meters (centimeters). Measurements should be carried out according to the parameters: length, width, thickness.

Calculation of the cubic capacity of an unedged board:

The calculation of cubature in this case also requires the measurement of length, width and height. The difference is that the calculation of the cubic capacity of one board becomes impossible, so we put the boards in a pack and measure it using various coefficients.

To make the calculations more reliable, it is recommended to stack the boards, then take the average of the thinnest and widest boards, add the two resulting indicators and divide in half. Thus, the average width is recognized, the width and length are measured traditional method.

In the next step, we multiply the stack width, length and width together and apply reduction factor. In accordance with GOST, this coefficient for a half-beam and for an unedged board is 0.5 and 0.63, respectively. Often, in order to simplify calculations, lumber manufacturers ship material with a coefficient of 0.7.

After one stack of lumber has been counted, you can move on to the second, third, etc.

columnar;
tape;
slab.

Obviously, the calculation of cubature in each individual case is individual. Let's start with the columnar foundation:

When calculating the cubature of a strip foundation, first we determine its cross section. If it is even, there should be no difficulty in calculating the cubature. In this case, we multiply the perimeter of the structure by its thickness and width. Next, follow the calculation instructions:

The cubic capacity of the slab foundation is calculated most simply. To determine the cubature of the slab base, you only need to multiply the length, width and thickness of the slab.

For example, it has the following data: 10, 0.4 and 10 meters. We calculate the volume by multiplying the indicators, and we get 40 m3 - the volume of concrete required.

However, it should be noted that in order to increase the strength of the slab foundation, they often resort to equipping the plates with stiffeners. If you are dealing with just such a project, in order to calculate the required amount of material, you need calculate separately the volume of the slab and ribs and add the resulting values.

So, we already know the indicator associated with the stove. It remains to calculate the cubic capacity of the stiffeners.

Suppose, in our case, the base has four reinforced elements with indicators of 10, 0.25 and 0.3 meters. Obviously, the volume of one stiffener is 0.75 meters. The total indicator for all ribs is 3 cubic meters (0.75 * 4). Then, to calculate the total amount of mortar required for the slab foundation, you need add the received values(40+3) and get 43 m³.

Calculation of the cubic capacity of the room

If the room you are interested in has a simple shape, then it is not difficult to calculate its cubic capacity: just multiply the exponents width, length and height of the room.

If you do not have one or more characteristics of the room, measure them using tape measure or rangefinder. In order to increase the accuracy of the measurements taken, you can measure the height and width of opposite walls twice, then add and divide the resulting value in half (find the arithmetic mean).

Let's say you know the area of the room. To find the cubic capacity, you need to multiply this indicator by the height.

If the room has complicated form, to begin with, conditionally divide the room into simple figures and, using geometric formulas, calculate the volume of each of them, then add the values.

Calculation of cubature from mass

If the mass of a substance is known for which it is necessary to calculate the volume (cubic capacity), one should first clarify the density this substance. This indicator can be measured independently or found in the density table of substances.

In order to find out the number of cubic meters, we should divide the known indicator of the mass of a substance by its density. In this case, the mass is measured in kilograms, and the density in kg / m3.

Non-standard methods for calculating cubature

If you are dealing with some kind of irregularly shaped body and at the same time you know the density of the material from which the body is made, you can use all known Archimedes' law. To do this, you just need to lower the body into water and measure the volume of water displaced from the vessel - this will be an indicator of the volume of the body immersed in water.

There is another way to calculate the cubature of a body. He quite laborious, however, in some cases is the only way out of the situation. So, you need to measure a cubic meter of material. This can be done with a bucket. If we are talking about a standard bucket, its capacity is 10 liters or 0.01 m3. Consequently, one hundred such buckets of the material of interest to us will be one cubic meter.

As you can see, the cubature calculation scheme in each individual case is very individual. Much depends on what indicators are already known and the volume of what exactly needs to be calculated. In any case, the calculation of the cubic capacity of a particular substance (concrete, water, sand, etc.) or premises very important not only in the professional field, but also in Everyday life. However, to produce necessary calculations It will not be difficult for a person who is absolutely not connected with the mathematical sciences.
