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.
Jerry wants to wrap a present in a box for his mother. The box measures 10 cm wide, 4 cm high, and 17 cm long. How much wrapping paper will Jerry need to wrap the present?
To calculate the amount of wrapping paper Jerry will need, we need to find the surface area of the rectangular prism.
The formula for the surface area of a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
Plugging in the measurements:
Surface Area = 2(10)(17) + 2(10)(4) + 2(17)(4)
Surface Area = 340 + 80 + 136
Surface Area = 556 square centimeters
Jerry will need 556 square centimeters of wrapping paper to wrap the present.
