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)

Answer 1

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.

Answer 3

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

Given measurements:
Length (l) = 17 cm
Width (w) = 10 cm
Height (h) = 4 cm

Substitute the values into the formula:
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.
