Jackie is wrapping a birthday present. The gift box is in the shape of a rectangular prism. It has a length of 8 inches, a width of 10 inches, and a height of 3 inches. What is the minimum amount of wrapping paper she will need to completely cover the box?

To cover the rectangular prism, find its surface area: 2(length × width + length × height + width × height). Substituting the measurements gives 2(8 × 10 + 8 × 3 + 10 × 3) = 2(80 + 24 + 30) = 268 square inches. Jackie needs 268 square inches of wrapping paper, choice A.
