To calculate the amount of wrapping paper needed, we need to find the surface area of the box.
The formula to find the surface area of a rectangular prism is 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height.
Plugging in the values:
Surface area = 2(17)(10) + 2(17)(4) + 2(10)(4)
Surface area = 340 + 136 + 80
Surface area = 556 square centimeters
So, Jerry will need 556 square centimeters of wrapping paper to wrap the present.
An illustration shows a rectangular prism with its length measuring 17 centimeters, width measuring 10 centimeters, and height measuring 4 centimeters. The edges that are not visible are marked as dashed lines.
