Question

A gift has the dimensions of 50 cm x 35 cm x 5 cm. You have wrapping paper with

dimensions of 75 cm x 60 cm. Do you have enough wrapping paper to wrap the gift? Why
or why not?

Answer 1

Yes, there is enough wrapping paper

The area of the wrapping paper is greater than area of the gift

Explanation:

What to do is to check the area of the wrapping paper and the gift if equal.

Looking at the dimensions of the gift, it is a cuboid

Area of a cuboid = 2(lb + lh + bh)

where l, b and h are 50, 35,5 respectively

= 2(250 + 175 + 1750)

= 4350 cm^2

The area of the wrapping paper is just the product of its side = 75 * 60 = 4500 cm^2

We can see clearly that the area of the wrapping paper is greater than area of the gift.

so we can conclude that it is enough to wrap the gift
