1. First, calculate the volume of the 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×h×b = 10×10×1 =100 Cu.F
2. Calculate the volume of the brick:
The standard size of a brick (IS Standard) is 190 mm ×90 mm ×90 mm and with the mortar joint, it becomes 200mm × 100 mm× 100 mm.
l = 200 mm= 0.656168 ft.
b = 100 mm =0.328084 ft.
h = 100 mm = 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.
