# The dimensions of a box are 50 cm × 36 cm × 25 cm. How many square cm of cloth is needed to make a cover for the box?

The box is like the shape of a cuboid

Length = l = 50 cm

Breadth = b = 36 cm

Height = h = 25 cm

Total surface area of cuboid = 2 × (lb + bh + lh)

total surface area of box = 2 × (50×36 + 36×25 + 50×25)

= 2 × (1800 + 900 + 1250)

= 2 × 3950

= 7900 cm2

Amount of cloth required to make cover = total surface area of box

Therefore, 7900 cm2 cloth will be required to make cover for the box
