Jose is constructing a house. He dug a pit in the ground in the shape of a rectangular block and laid plastic shut in it to collect water. The internal length, breadth and height of the pit are 2 metre, 1 metre and 80 centimetre. Find the amount of water that the pit holds.

Open in App

Solution

Length of the pit = 2 m = 2 × 100 cm = 200 cm

Breadth of the pit = 1 m = 1 × 100 cm = 100 cm

Height of the pit = 80 cm

Volume of the pit = Length × Breadth × Height

= 200 cm × 100 cm × 80 cm

= 1600000 cm³

= (1 litre = 1000 cu. cm)

= 1600 litres

Therefore, the pit can hold 1600 litres of water.
