1.	The measures of a box are 50 cm × 36 cm × 25 cm. To make the cover of the box. How much cloth is needed?
Answer» Given Length of box (l) = 50 cm Breadth of box (b) = 36 cm Height of box (h) = 25 cm The necessary cloth to make its cover = surface area of the box = 2(lb + bh + hl) = 2[(50 × 36) + (36 + 25) + (25 + 50)] = 2[1800 + 900 + 1250] = 2 × 3950 = 7900 cm².

The measures of a box are 50 cm × 36 cm × 25 cm. To make the cover of the box. How much cloth is needed?

Answer»

Given

Length of box (l) = 50 cm

Breadth of box (b) = 36 cm

Height of box (h) = 25 cm

The necessary cloth to make its cover = surface area of the box

= 2(lb + bh + hl)

= 2[(50 × 36) + (36 + 25) + (25 + 50)]

= 2[1800 + 900 + 1250]

= 2 × 3950 = 7900 cm².
