How many bricks will be required to construct a wall 8m long, 6m high and 22.5 cm thick if each brick measures `(25 cm xx 11.25 cm xx 6 cm)` ?

Answer

6400

Explanation

Required number of bricks `= ("volume of the wall in "cm^(3))/("volume of 1 brick in "cm^(3))`
`= (800 xx 600 xx 22.5)/(25 xx 11.25 xx 6)`
