To find the surface area of the prism, we need to find the area of all six sides and add them together.
The formula for the surface area of a rectangular prism is:
SA = 2lw + 2lh + 2wh
Where l = length, w = width, and h = height.
Substituting the given values, we get:
SA = 2(15 x 3) + 2(15 x 4) + 2(3 x 4)
SA = 90 + 120 + 24
SA = 234
Therefore, the surface area of the prism is 234 square millimeters.
