A wall of length 10 m was to be built across an open ground. The height of the wall is 4 m and thickness of the wall is 24 cm. If this wall is to be built up with bricks whose dimensions are 24 cm×12 cm×8 cm, how many bricks would be required?
Answers
The number of bricks required to build the wall = 4166.66
Length of the wall = 10 m = 1000 cm
Height of the wall = 4 m = 400 cm
Width of the wall = 24 cm
Total volume of the wall to be built = 1000 × 400 × 24
= 9600000 cm³
The dimension of the bricks are 24 cm × 12 cm × 8 cm
Volume of 1 bricks = 24 × 12 × 8
= 2304 cm³
Number of bricks required to build the wall = Volume of the wall / volume of one brick
= 9600000/2304
= 4166.66
Answer: Length of wall = 10 m
Height of wall = 4 m
Thickness of wall = 24 cm or 0.24 m
Volume of wall = Length×breadth×height
= 10×4×0.24 = 9.6 m³
Dimensions of brick = 24 cm×12 cm×8 cm or 0.24 m×0.12 m×0.08 m
Volume of brick = 0.24 m×0.12 m×0.08 m = 0.002304 m³
Therefore Number of bricks required = Volume of wall ÷ Volume of 1 brick
= 9.6 m³ ÷ 0.002304 m³
= 4166.66 (approx)
