Write an expression for the total Surface Area (SA) of a rectangular prism whose base is a square with side of length x and height of y.

For this case we have the following expression:

S. A = 2x ^ 2 + 2x * y + 2x * y

Rewriting we have:

S. A = 2x ^ 2 + 4x * y

S. A = 2 (x ^ 2 + 2x * y)

Where,

x: side length of a square base

y: height of the prism

Answer:

an expression for the total Surface Area (SA) of a rectangular prism is:

S. A = 2 (x ^ 2 + 2x * y)
