A Book is to be sent as a gift to a person.
The shopkeeper has to gift wrap the book which is in a box of dimensions 20cm × 10cm × 5cm. The quantity of gift wrap(assuming negligible thickness) required would be___________.
700cm2
The gift wrapper wraps all the 6 faces of the box. Therefore, we have to apply total surface area.
Therefore amount of paper required = 2(200 + 50 + 100) = 700 cm2 of paper.
