Question

A rectangular cardboard sheet has length 32 cm and breadth 26 cm. Squares each of side 3 cm, are cut from the corners of the sheet and the sides are folded to make a rectangular container. Find the capacity of the container formed.

Answer 1

Length of sheet = 32 cm

Breadth of sheet = 26 cm 

Side of each square = 3cm

∴  Inner length = 32 - 2 x 3 = 32 - 6 = 26 cm

Inner breadth = 26 - 2 x 3 = 26 - 6 = 20 cm

By folding the sheet, the length of the container = 26 cm

Breadth of the container = 20 cm and height of the container = 3 cm

∴ Vol. of the container = l x b x h

= 26 cm x 20 cm x 3 cm = 1560 cm³
