Answer: 38832

The surface area of a rectangular prism is found by adding the areas of all six faces. The front and back faces have an area of 104.4mm x 60mm each, or 6264 square millimeters each. The top and bottom faces have an area of 80mm x 104.4mm each, or 8352 square millimeters each. The two side faces have an area of 80mm x 60mm each, or 4800 square millimeters each.

Adding all of these areas together, we get:

6264 + 6264 + 8352 + 8352 + 4800 + 4800 = 38832

Therefore, the surface area of the rectangular prism is 38,832 square millimeters.
