To find the surface area of a rectangular prism, you need to calculate the area of all six faces and add them together.
The formula for the surface area of a rectangular prism is:
SA = 2lw + 2lh + 2wh
Where l, w, and h are the length, width, and height, respectively.
Plugging in the numbers from the problem gives:
SA = 2(17)(3) + 2(17)(6) + 2(3)(6)
SA = 102 + 204 + 36
SA = 342 cm^2
Therefore, the answer is D. 342 cm^2.
