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
