Use formula to determine the surface area of a right rectangular prism where each edge length measures 12.75 cm.

Question

A. 76.5 cm^2
B. 975.38 cm^2
C. 459 cm^2
D. 5,852.25 cm^2

Answer 1

The formula to determine the surface area of a right rectangular prism is:

Surface Area = 2lw + 2lh + 2wh

Given that each edge length measures 12.75 cm, we have:
l = 12.75 cm
w = 12.75 cm
h = 12.75 cm

Substituting these values into the formula, we get:
Surface Area = 2(12.75)(12.75) + 2(12.75)(12.75) + 2(12.75)(12.75)
Surface Area = 2(162.5625) + 2(162.5625) + 2(162.5625)
Surface Area = 325.125 + 325.125 + 325.125
Surface Area = 975.375

Therefore, the surface area of the right rectangular prism is 975.38 cm^2.

The answer is B.
