A candy bar is shown below.  How much paper is needed to wrap the sides of the candy bar?

• 156 inches ²

• 126 inches ²

• 130 inches ²

• 155 inches ²

Answer explanation

To calculate the paper needed to wrap the sides of the candy bar, find the perimeter of the candy bar. Perimeter = 2(length + width) = 2(10 + 8) = 2(18) = 36 inches. Therefore, 36 inches squared is needed for the sides, which is 126 inches^2.
