The formula for the surface area of a rectangular prism with a square base is SA=2s2+4shSA=2s2+4sh. What is the surface area of this rectangular prism if s=3s=3 and h=5?

This is the concept of algebra, given that the formula for the surface area of the prism is modeled by the expression SA=2s²+4sh, the surface area of the prism when s=3 and h=5 will be found by substituting the values in our expression as follows;

SA=2 (3) ²+4*3*5

SA=2 (9) + 60

SA=18+60

SA=78 sq. units

The answer is 78 sq. units
