Question

how many bricks each measuring 25 cmx11.25 cm x 6 CM will be needed to build a wall 8 metre long 6 metre high and 22.5 CM thick?​

Answer 1

Answer:

Let no. of bricks be x

volume of wall = 800×600×22.5 cubic centimetre (1m=100cm)

volume of one brick = 11.25×25×6 cubic centimetre

volume of wall = volume of x bricks

therefore, 800×600×22.5 = 11.25×25×6×x

⇒ 10800000 = 1687.5×x

⇒ x = 6400 bricks

∴Answer = 6400 bricks
