The surface area of the rectangular prism is 90 square units.

To find the surface area of the rectangular prism, we substitute the given values of s and h into the formula SA = 2s² + 4sh.

SA = 2(3)² + 4(3)(6)

SA = 2(9) + 4(3)(6)

SA = 18 + 72

SA = 90

Therefore, the surface area of the rectangular prism is 90 square units.
