A gift box is 14 inches long, 8 inches wide, and 4 inches high. How much wrapping paper is needed to wrap the gift box?

A) 200 in

B) 350 in

C) 400 in

D) 550 in

We will use the formula for finding the surface area of a rectangular prism.

Formula =

SA = 2 (w l + h l + h w) SA = 2 (8·14 + 4·14 + 4·8)

SA = 2 (112 + 56 + 32)

SA = 2 (200)

SA = 400

The gift box needs C) 400 in wrapping paper to wrap the gift box.
