Question

A rectangular gift box is 10 inches long, 7 inches wide, 1.25 inches high, and had a surface area of 182.5 square inches. gift wrap costs $0.012 per square inch. how much does it cost to wrap the box if you use the least possible amount of gift wrap to cover the entire box

Answer 1

The answer is $2.19 because you have to multiply the surface area by the cost per square inch. So, 182.5 times 0.012=2.19

Answer 2

The measurements of the box actually aren't needed since they already gave you the surface area. Just multiply the given surface area by the price of wrapping paper per square inch: 182.5 x $0.012 = $2.2224. If you round that answer, you'll know that it costs $2.22 to wrap the gift.
