Question

A gift box has the shape of a rectangular prism. How much wrapping paper do you need to cover the​ box?

(50 points if correct) and only answer needed

Answer 1

Answer: 648 in^2 of wrapping paper.

Explanation:

The question is asking for the surface area of the prism. The dimensions of the prism are 16inX13inX4in.

All we need to do is find the area of all the surfaces and add them. So:

2(16x4)+2(13x4)+2(16X13) is our expression.

2(16x4)= 2x64= 128

2(13x4)= 2x52= 104

2(13x16)= 2x208= 416

Finally, we add:

128 + 104 + 416 = 648

Therefore, 648 in^2 of wrapping paper is needed to cover the box.
