Answer 1

To find the surface area of a right rectangular prism, you need to calculate the total area of all six faces.

The formula for the surface area of a right rectangular prism is:
Surface Area = 2lw + 2lh + 2wh

Where:
l = length
w = width
h = height

Given that each edge length measures 12.75 cm, you can substitute this value into the formula.

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 975.375 cm2 or 975.375 cm squared.
