A wall of length 10m was to be built across an open ground. The height of wall is 4m and thickness is 24 cm. If this wall is to be built up with bricks whose dimensions are 24cm×12cm×8cm, how many bricks would be required?

To get the no.of bricks needed we need to divide the volume of the wall by the volume of a single brick.That will be equal to 1000×400×24/24×12×8=12500/3=4166.66

Length of wall = 10m
Height of wall = 4m
Thickness of wall = 24cm or 0.24m
Volume of wall = Length×breadth×height
= 10×4×0.24 = 9.6 m³
Dimensions of brick = 24cm×12cm×8cm or 0.24m×0.12m×0.08m
Volume of brick = 0.24m×0.12m×0.08m = 0.002304 m³
Therefore Number of bricks required = Volume of wall ÷ Volume of 1 brick
= 9.6 m³ ÷ 0.002304 m³
= 4166.66 (approx)
Therefore,Number of bricks required to make the wall= 4166(approximately)
