To find the surface area of a right rectangular prism, we use the formula:
Surface Area = 2lw + 2lh + 2wh
In this case, each edge length measures 12.75 cm.
Let's substitute the given values into the formula:
Surface Area = 2(12.75 cm)(12.75 cm) + 2(12.75 cm)(12.75 cm) + 2(12.75 cm)(12.75 cm)
Simplifying the expression,
Surface Area = 2(162.5625 cm^2) + 2(162.5625 cm^2) + 2(162.5625 cm^2)
Surface Area = 325.125 cm^2 + 325.125 cm^2 + 325.125 cm^2
Surface Area = 975.375 cm^2
Therefore, the correct answer is:
975.38m^2.
