How many bricks will be required to construct a wall 8 m long, 6 m high and 22.5 cm thick if each brick measures (25cm × 11.25 cm × 6cm)?
Volume of a cuboid = Length × Breadth × Height
1 m =100 cm
Volume of wall = 8 m × 6 m × 0.225 m = 10.8 m3
Volume of a brick = 0.25 m × 0.1125 m × 0.06 m = 0.0016875 m3
No. of bricks =
= 6400
