Question

if one brick measures 25 CM in length, 12 CM in width and 8 cm in height, how many such bricks will be needed to build a wall 3 metre long, 1.6 metre tall and 25 CM thick




pls say the correct answer if u know​

Answer 1

Volume of 1 brick = lbh

= (0.25 × 0.12 × 0.08) m³

= 0.0024 m³

Volume of the wall = lbh

= 3 × 1.6 × 0.25

= 1.2 m³

No. of bricks required to build a wall

= Volume of wall / Volume of a brick

= 1.2/0.0024

= 500
