A mason constructs a wall of dimensions...

A mason constructs a wall of dimensions 5 m x 40 cm x 3 m with bricks each 25 cm x 10 cm x 15 cm. Calculate the total number of bricks used.

Text Solution

Verified by Experts

volume of wall= `500 xx 40 xx 300= 6000000cm^3`
volume of 1 brick = `25 xx 10 xx 15 = 3750 cm^3`
no of bricks used= `(500 xx 40 xx 300)/(25 xx 10 xx 15)`
`= 20 xx 4 xx 20`
`= 1600` bricks
