Answer 2

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

Step-by-step explanation:

Length of brick = 25 cm

Breadth of brick = 11.25 cm

Height of brick = 6 cm

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

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 = $Length \times Breadth \times Height = 800 \times 600 \times 225 =108000000 cm^3$

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

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