Question

A samsung tablet is to be sent as a gift to a person. The shopkeeper has to wrap the tablet which is in a box of dimensions 20 cm $\times$ 10 cm $\times$ 5 cm. How much paper would be required to wrap it? (assuming negligible thickness)

• A. 500$c{m}^3$
• B. 300$c{m}^2$
• C. 1000$c{m}^3$
• D. 700$c{m}^2$

Answer 1

The correct option is D

700$c{m}^2$

Length = 20 cm
Breadth = 10 cm
​Height = 5 cm

We have to cover all the 6 faces of the box. So, we have to apply total surface area.
Amount of paper required = 2 (lb + bh + lh)
= $2(20\times 10+5\times 10+20\times 5)$
= $2(200+50+100)$
= $700c{m}^2$
