CALCULATION OF BRICKS IN A WALL

Estimation of building materials is essentially required before starting a new construction project.
Today we are going to see the easiest method to calculate the required number of bricks in a wall.So let's start from the beginning.

REQUIRED DATA:

• Volume of wall
• Volume of a standard brick
• Details of openings in the wall 

PROCEDURE:

1. First calculate the volume of wall to be built. 

Let us assume,
The length of the wall(L) = 10 foot.
The height of the wall (H) = 10 foot.
Thickness of the wall (B) = 1 foot.

 Calculate the volume of the wall by multiplying the length,height,and thickness.
∴Volume of the wall = L*B*H

∴ Volume of the wall = L*B*H = 10*10*1 = 100 Cu.F

2.Calculate the volume of the brick

The standard size of the brick is 190mm*90mm*90mm (IS standard) and with the mortar joint, it becomes 200mm*100mm*100mm.

L = 200mm = 0.656168 ft.
B = 100mm = 0.328084 ft.
H = 100mm = 0.328084 ft.
 
∴Volume of the brick = L*B*H = 0.656168*0.328084*0.328084 = 0.0706 Cu.F

3. To find out the total nos. of brick, divide the volume of wall by the volume of the brick.

∴No. of bricks required = 100 / 0.0706 = 1416 no. of bricks.

NOTE:
1. Consider 10% wastage of bricks.
2. If the wall has any openings, subtract the volume of the openings from the volume of wall and then divide it by the volume of brick.
