Justify the formula, and find the surface area of the right rectanglar prism using nets or decomposition.
The numbers are, 2 ft, 3 ft, and 8ft.
A. 72 square feet
B. 36 square feet
C. 72 feet
D. 48 cubic feet
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 the numbers are 2 ft, 3 ft, and 8 ft, we can plug these values into the formula:
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 closest option is A. 72 square feet, but the calculated surface area is 92 square feet.
