Solution
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
