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 (25 cm × 11.25 cm × 6 cm)?
Given,
Dimensions of wall = 8m × 6m × 22.5 cm = 800 cm × 600 cm × 22.5 cm
Dimensions of each brick = 25 cm × 11.25cm × 6 cm
Hence,
Number of bricks required = 
5
