Naomi wants to wrap a gift for her sister. The gift is in a box with a length of 10 inches, a height of 2 inches, and a depth of 3 inches. If Naomi is calculating the minimum amount of wrapping paper to wrap the gift, would she be finding the Volume or Surface Area?

To calculate the minimum amount of wrapping paper needed to wrap the gift, Naomi would be finding the Surface Area.

The Surface Area of a three-dimensional object is the sum of the areas of all its faces. In this case, the gift is a rectangular prism with dimensions of length 10 inches, height 2 inches, and depth 3 inches.

To wrap the gift, Naomi would need to cover all six faces of the rectangular prism with wrapping paper. The formula for the Surface Area of a rectangular prism is:

Surface Area = 2lw + 2lh + 2wh

where l, h, and w are the length, height, and width of the rectangular prism, respectively.

Substituting the values for the length, height, and depth of the gift, we get:

Surface Area = 2(10 x 2) + 2(10 x 3) + 2(2 x 3)

Surface Area = 20 + 60 + 12

Surface Area = 92 square inches

Therefore, Naomi would need at least 92 square inches of wrapping paper to cover the gift, which is the Surface Area of the rectangular prism.
