How many bricks each measuring 25 cm 12.5 cm 16 cm will be needed to construct a wall 8 m long. 5 m high and 22.5 cm thick?

1800

We know that,

Volume of wall = (Length × Breadth × Height)

also,

Volume of wall = x × Volume of one brick

Bricks measurement = 25 cm × 12.5 cm × 16 cm

Wall measurement = 8 m × 5 m × 22.5 cm

We have,

Volume of wall = 800 × 500 × 22.5 = 9000000 cm³

Volume of Bricks = 25 × 12.5 × 16 = 5000 cm³

Number of bricks = \(\frac{9000000 }{5000 }\) = 1800
