Answer:

Number of bricks required = 6400

Step-by-step explanation:

The dimensions of the wall are

Length = 8m = 800 cm

Breadth = 6m = 600 cm

Height = 22.5 cm

We know that

Volume of wall = l × b × h

By substituting the values

Volume of wall = 800 × 600 × 22.5

By multiplication

Volume of wall = 10800000 cm3

The dimensions of brick are

Length = 25cm

Breadth = 11.25cm

Height = 6cm

We know that

Volume of brick = l × b × h

By substituting the values

Volume of brick = 25 × 11.25 × 6

By multiplication

Volume of brick = 1687.5 cm3

So the number of bricks required = Volume of wall/ Volume of brick

By substituting the values

Number of bricks required = 10800000/1687.5

By division

Number of bricks required = 6400
