The surface area of a rectangular prism can be found by adding up the areas of all its faces.
The top and bottom faces have the dimensions 12 inches by 5 inches, which gives an area of 12 x 5 x 2 = 120 square inches.
The front and back faces have the dimensions 12 inches by 3 inches, which gives an area of 12 x 3 x 2 = 72 square inches.
The left and right faces have the dimensions 5 inches by 3 inches, which gives an area of 5 x 3 x 2 = 30 square inches.
Adding up all the areas, we get 120 + 72 + 30 = 222 square inches.
Therefore, the surface area of the rectangular prism is 222 square inches.
