D. 48 cubic feet

1 answer

First, let's calculate the surface area of the right rectangular prism.

The formula for the surface area of a rectangular prism is 2(lw + wh + lh), where l is the length, w is the width, and h is the height.

Given the dimensions of the prism are 2 ft, 3 ft, and 8 ft, we can plug these values into the formula:

Surface Area = 2(2*3 + 3*8 + 8*2)
Surface Area = 2(6 + 24 + 16)
Surface Area = 2(46)
Surface Area = 92 square feet

Therefore, the correct answer is not listed among the options provided. The surface area of the right rectangular prism is 92 square feet.
