Calculate the cubic meter of the wall. How to find the volume of a room. Converting square meters to cubic

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 the start of construction, it is not easy to calculate the required amount of 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 different amount 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.

Recently, questions have been received about the construction of aerated concrete, questions on the projects of purchased houses, recalculation of one size to another, etc. from visitors to our site DCI GROUP.
How to calculate the cubature of a gas block for the construction of a cottage, if I only have a total square of walls of 234 m 2?

Everything is not difficult at all! There are two options for converting the quadrature of walls into the cubic capacity of aerated concrete products.

Complex calculation with lots of data (in 4 steps):

Based on the total quadrature of the walls of your house at 234 m 2, we will calculate on the four main dimensions of aerated concrete blocks (cellular blocks).
Commonly used sizes:

	Width, mm	Height, mm.	Length, mm.
Aerated concrete H+H Block Extra	365	250	625
Aerated concrete H+H Block	360	240	590
AAC aerated concrete (ZSM No. 1)	400	200	600
AAC aerated concrete (ZSM No. 1)	360	200	600

2. Knowing the square of one aerated concrete block, we will calculate how many aerated concrete blocks we need to build your walls. To do this, we divide the total quadrature of your walls by the resulting quadrature of one aerated concrete block:

3. Stage number 3, find out the volume of one aerated concrete block ( cubic meter as much as one block of aerated concrete, m 3). To do this, you need to multiply the width, height, height among themselves:

Manufacturer cellular concrete	Calculation
Aerated concrete H+H Block Extra	0.365m 2 x 0.25m 2 x 0.625m 2 \u003d 0.05703125 m 3
Aerated concrete H+H Block	0.36m 2 x 0.24m 2 x 0.59m 2 \u003d 0.050976 m 3
AAC aerated concrete (ZSM No. 1)	0.40m 2 x 0.20m 2 x 0.60m 2 = 0.048 m 3
AAC aerated concrete (ZSM No. 1)	0.36m 2 x 0.20m 2 x 0.60m 2 \u003d 0.0432 m 3

4. The final stage, Our exhausting calculations. We find out the required cubic capacity of aerated concrete based on their 234 m 2. Quantity, pcs. aerated concrete blocks multiply by the cubic capacity of one aerated concrete block:

Aerated concrete manufacturer	Calculation
	1497.6 pcs. x 0.05703125 m 3 \u003d 85.41 m 3
Aerated concrete H+H Block(360 mm.)	1652.5 pcs. x 0.050976 m 3 \u003d 84.24 m 3
	1950 pcs. x 0.0432 m 3 \u003d 96.60 m 3
	1950 pcs. x 0.0432 m 3 \u003d 84.24 m 3

Optimal calculation (in 1 stage):

Not many people use this method, but it is much simpler than long-term calculations with a lot of data (m 2, m 3, pcs.).

And so, about the optimal calculation. How to find out the cubic capacity of the required volume of aerated concrete, based only on the data of the total quadrature of the walls of the house at 234 m 2 and the desired wall width in meters. For such a calculation, we will operate with the width of the aerated concrete block we need (365 mm, 360 mm and 300 mm) and multiply by the total cubic capacity of the walls:

Aerated concrete manufacturer	Calculation
Aerated concrete H+H Block Extra (365 mm.)	243 m 2 x 0.365 m = 85.41 m3 3
Aerated concrete H+H Block(360 mm.)	234 m 2 x 0.36 m = 84.24 m3 3
AAC AAC (ZSM No. 1) (400m)	234 m 2 x 0.36 m = 96.60 m3
AAC aerated concrete (ZSM No. 1) (360 mm.)	234 m 2 x 0.30 m = 84.24 m3

Peter, Chelyabinsk asks a question:

Hello. I'm building in the summer country house near the city. I decided to make it out of brick. Due to the difficult economic situation and constantly rising prices, I decided to purchase bricks in advance. Therefore, I would like you to help me answer the question of how to calculate cubic capacity brickwork. I have not yet decided on the thickness of the wall, everything will depend on my financial resources for the purchase of the required amount of bricks. Therefore, I would like to know how to calculate the number of bricks for walls of different thicknesses. And how difficult is it, can I cope with the calculations myself? Thanks in advance for your reply!

The expert answers:

The volume of the required number of bricks depends on the chosen masonry method.

Hello! This is very good decision- to purchase the main building material in advance, because no one knows whether the prices for a brick block will skyrocket this year or remain the same. The economy has been unpredictable lately.

There are few formulas that allow you to answer the question of how to calculate the cubic capacity of brickwork, and they are quite simple. To calculate, you absolutely do not need to have any additional knowledge in the field of mathematics, it will be enough to have the basic foundations. Even a schoolboy can cope with calculations.

In order for you to correctly calculate the cost of the purchase, you need to take into account not only the cost of the building material itself, but also its delivery and unloading.

The width of the wall directly depends on the blocks laid in it. The standard length is 25 cm. If the building is half a block, this means that the width of the wall is 12 cm. 1.5 bricks is 38 cm (12 cm + 25 cm + 1 cm per seam). 2 - 51 cm; 2.5 - 64 cm.

Thickness standard in middle lane RF is 1.5-2.5 bricks. To determine the required amount of basic building material, you need to calculate the cubic meters of the whole house. The first step is to find out the length of the perimeter of the building, you can do this with a tape measure or see its length in the project, if you have one. Measure along and across, if the windows are different, it will complicate things a bit. Multiplying these parameters, get the area of the windows. Do the same for all doorways.

After the cubic meters of the house openings are calculated, they must be subtracted from the total cubic meters of the house.

When calculating, keep in mind that the length and width of all bricks are the same, but the height can be different: 6.5 cm; 8.8 cm and 13.8 cm.

Thus, for 1 sq.m of a wall of single brick they will need 50. From one and a half - 39 pcs. if from a double - 26 pcs.

To get the required amount of material, you need to multiply the area by the number of bricks spent per 1 sq.m. To get the final result, multiply by 2 if the wall is 1 brick; by 3 if in 1.5; by 4 if in 2.

Now you know how to calculate the cubic capacity of brickwork yourself. In any case, all the calculations that you make will be approximate, the exact amount of material cannot be calculated. But there is nothing to worry about, because you can always buy the missing amount of building materials. Good luck with your construction!

Measure everything necessary distances in meters. The volume of many three-dimensional figures is easy to calculate using the appropriate formulas. However, all values substituted into the formulas must be measured in meters. Thus, before substituting values into the formula, make sure that they are all measured in meters, or that you have converted other units of measurement to meters.

1 mm = 0.001 m
1 cm = 0.01 m
1 km = 1000 m

To calculate the volume of rectangular shapes (rectangular box, cube) use the formula: volume = L × W × H(length times width times height). This formula can be considered as the product of the surface area of one of the faces of the figure and the edge perpendicular to this face.

For example, let's calculate the volume of a room with a length of 4 m, a width of 3 m and a height of 2.5 m. To do this, simply multiply the length by the width by the height:
- 4×3×2.5
- = 12 × 2.5
- = 30. The volume of this room is 30 m 3.
A cube is a three-dimensional figure in which all sides are equal. Thus, the formula for calculating the volume of a cube can be written as: volume \u003d L 3 (or W 3, or H 3).

To calculate the volume of figures in the form of a cylinder, use the formula: pi× R 2 × H. The calculation of the volume of a cylinder is reduced to multiplying the area of the round base by the height (or length) of the cylinder. Find the area of the circular base by multiplying pi (3.14) by the square of the circle's radius (R) (the radius is the distance from the center of the circle to any point on that circle). Then multiply the result by the height of the cylinder (H) and you will find the volume of the cylinder. All values are measured in meters.

For example, let's calculate the volume of a well with a diameter of 1.5 m and a depth of 10 m. Divide the diameter by 2 to get the radius: 1.5/2=0.75 m.
- (3.14) × 0.75 2 × 10
- = (3.14) × 0.5625 × 10
- = 17.66. The volume of the well is 17.66 m3.

To calculate the volume of a sphere, use the formula: 4/3 x pi× R 3 . That is, you only need to know the radius (R) of the ball.

For example, let's calculate the volume hot air balloon 10 m in diameter. Divide the diameter by 2 to get the radius: 10/2=5 m.
- 4/3 x pi × (5) 3
- = 4/3 x (3.14) x 125
- = 4.189 × 125
- = 523.6. The volume of the balloon is 523.6 m 3.

To calculate the volume of figures in the form of a cone, use the formula: 1/3 x pi× R 2 × H. The volume of a cone is 1/3 of the volume of a cylinder that has the same height and radius.

For example, let's calculate the volume of an ice cream cone with a radius of 3 cm and a height of 15 cm. Converting to meters, we get: 0.03 m and 0.15 m, respectively.
- 1/3 x (3.14) x 0.03 2 x 0.15
- = 1/3 x (3.14) x 0.0009 x 0.15
- = 1/3 × 0.0004239
- = 0.000141. The volume of an ice cream cone is 0.000141 m 3.

To calculate the volume of figures, do not correct form use multiple formulas. To do this, try to break the figure into several shapes of the correct shape. Then find the volume of each such figure and add up the results.

For example, let's calculate the volume of a small granary. The storage has a cylindrical body 12 m high and a radius of 1.5 m. The storage also has a conical roof 1 m high. By calculating the volume of the roof and the volume of the body separately, we can find the total volume of the granary:
- pi × R 2 × H + 1/3 x pi × R 2 × H
- (3.14) x 1.5 2 x 12 + 1/3 x (3.14) x 1.5 2 x 1
- = (3.14) × 2.25 × 12 + 1/3 x (3.14) × 2.25 × 1
- = (3.14) × 27 + 1/3 x (3.14) × 2.25
- = 84,822 + 2,356
- = 87.178. The volume of the granary is 87.178 m3.

Concrete mortars are used for the construction of the foundation, the erection of walls and the pouring of the floor. Before the start of activities, it is important to choose the design of the foundation, correctly calculate the total level of costs and determine the required amount of building materials. Knowing how to calculate the volume of concrete, you can determine the estimated cost of construction activities, accurately plan the duration of the implementation concrete work and avoid unexpected costs. Let us dwell in detail on the methodology for performing calculations for various, as well as walls and floors.

Strip foundation scheme

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 foundation is calculated. On the design stage the need for a solution for pouring is calculated monolithic walls and concrete floor. 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

To receive 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. At the same time, in without fail the part of the foundation poured into the ground is also taken into account. 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 tape bases, 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.

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 intersections 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 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 the strength of the 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 a slab foundation has a complex configuration, then it should be divided on the plan into simpler figures, and then calculate the area and volume for each.

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

Calculator for calculating the amount of concrete per strip foundation Online

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- total area 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 rough surface has a bias. 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.
