Buddy the Elf needs to wrap a rectangular present that has a length of 18 inches, a width of 12 inches, and a height of 8 inches. He has a roll of wrapping paper that is 875 square inches. Does he have enough wrapping paper to wrap his present? Explain your answer.

Answer 1

To determine if Buddy has enough wrapping paper to wrap his present, we need to calculate the total surface area of the present.

The surface area of a rectangular prism is given by the formula 2(length*width) + 2(length*height) + 2(width*height).

Plugging in the given dimensions:
2(18*12) + 2(18*8) + 2(12*8)
= 432 + 288 + 192 = 912 square inches.

Since the surface area of the present is 912 square inches, and Buddy has a roll of wrapping paper that is only 875 square inches, he does not have enough wrapping paper to wrap his present.
