The formula for finding the surface area of a right rectangular prism is 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height.
Given:
Length (l) = 2 ft
Width (w) = 3 ft
Height (h) = 8 ft
Plugging in the values:
Surface Area = 2(2)(3) + 2(2)(8) + 2(3)(8)
Surface Area = 12 + 32 + 48
Surface Area = 92 square feet
Therefore, the correct answer is not listed. The surface area of the right rectangular prism is 92 square feet.
Justify the formula, and find the surface area of the right rectanglar prism.
The numbers are, 2 ft, 3 ft, and 8ft.
A. 72 square feet
B. 36 square feet
