First, we can find the surface area of the right rectangular prism by using the formula:

Surface Area = 2lw + 2lh + 2wh

Plugging in the given dimensions:

Surface Area = 2(2)(3) + 2(2)(8) + 2(3)(8)
Surface Area = 12 + 32 + 48
Surface Area = 72 square feet

Therefore, the surface area of the right rectangular prism is 72 square feet.

Correct response: 72 square feet
