Question

How many brisks are need to build a wall of length 44 meter, height 1.5 meter and broad 85 cm. The measurement of each brick is 20 cm × 10 cm × 17 cm.

Answer 1

Length of the wall = 44 meter

= 44 × 100 cm = 4400 cm

height = 1.5 meter = 1.5 × 100 = 150 cm

width of the wall = 85 cm

volume of the wall = length × breadth × height

= 4400 × 85 × 150 cm³.

length of one brick = 22 cm

breadth = 10 cm

height = 17 cm

The volume of a brick 22 × 10 × 17 cm³.

Hence, 15000 bricks will be needed.
