Question

How many bricks each measuring 25 cm × 11.25 ×6 will be needed to build a wall 8 m long 6 m high and 2.25 m thick​

Answer 1

Step-by-step explanation:

Length of brick = 25 cm

Breadth of brick = 11.25 cm

Height of brick = 6 cm

Volume of brick =Length \times Breadth \times Height = 25 \times 11.25 \times 6=1687.5 cm^3Length×Breadth×Height=25×11.25×6=1687.5cm

Length of wall = 8 m = 800 cm

Breadth of wall = 6 m = 600 cm

Height of wall = 2.25 m = 225 cm

Volume of wall = Length \times Breadth \times Height = 800 \times 600 \times 225 =108000000 cm^3Length×Breadth×Height=800×600×225=108000000cm

3

No. of bricks required = \frac{108000000}{1687.5}=64000

1687.5

108000000

=64000

Hence 64000 bricks each measuring 25cm×11.25cm× 6cm will be needed to build a wall 8m long 6m high and 2.25m thick
