Question

What is the least amount of wrapping paper needed to wrap a gift box that measures 8 inches by 8 inches by 10 inches.

Answer 1

The first thing we must do for this case is to find the surface area of the rectangular prism.

We have then:

`A = 2 * (l * h) + 2 * (h * w) + 2 * (w * l)`

Where,

w: width

l: long

h: height

Substituting values we have:

`A = 2 * (10 * 8) + 2 * (8 * 8) + 2 * (8 * 10)`

`A = 448 \ in ^ 2`

Answer:

the least amount of wrapping paper needed to wrap the gift box answer is:

A = 448 in²
