# A mason construct

Given: A wall of dimension (270 cm × 300cm × 350cm).

A wall of dimension (22.5cm × 11.25cm × 8.75cm).

space is covered by the mortar.

Here volume of the wall is covered by mortar, 1 – = volume of the wall is covered by bricks.

Volume of the cuboid is given by: lbh (here l, b, h are length , breadth, height respectively).

Let V1 be the volume of the wall.

V1 = l × b × h = 270 × 300 × 350

V1 = 270 × 300 × 350 = 28350000 cm2

Let V2 be the volume of the brick.

V2 = l × b × h = 22.5 × 11.25 × 8.75

V2 = 22.5 × 11.25 × 8.75 = cm2

Let ‘n’ be the number of bricks required to occupy volume of the wall.

n × = 28350000 ×

n = 28350000 × × = 11200

n = 11200

That is 11200 bricks required to occupy volume of the wall.
