Use the image to answer the question.
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?
(1 point)
To find the amount of wrapping paper needed, we need to calculate 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 given measurements:
Length (l) = 17 cm
Width (w) = 10 cm
Height (h) = 4 cm
Surface Area = 2(17)(10) + 2(17)(4) + 2(10)(4)
Surface Area = 340 + 136 + 80
Surface Area = 556
Therefore, Jerry will need 556 cm^2 of wrapping paper to wrap the present.
