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

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

Surface Area = 2(length × width) + 2(length × height) + 2(width × height)

Since each length measures 12.75 cm, the length (L) is 12.75 cm.

Therefore, the surface area of the right rectangular prism is:
Surface Area = 2(12.75 × width) + 2(12.75 × height) + 2(width × height)
