The surface area of a rectangular prism can be found by adding up the area of each face. So, the surface area of the rectangular prism with dimensions 12, 5, and 3 would be:
2(12 x 5) + 2(12 x 3) + 2(5 x 3) = 240 + 72 + 30 = 342 square inches
Therefore, the closest option to the answer is 3. 222 square inches.
