To find the surface area of a rectangular prism, you need to calculate the area of each face and then add them all together.
1. Area of the base: 12 in * 3 in = 36 square inches
2. Area of the top: 12 in * 3 in = 36 square inches
3. Area of the front face: 12 in * 3 in = 36 square inches
4. Area of the back face: 12 in * 3 in = 36 square inches
5. Area of the left side: 3 in * 3 in = 9 square inches
6. Area of the right side: 3 in * 3 in = 9 square inches
Adding all the areas together:
36 + 36 + 36 + 36 + 9 + 9 = 162 square inches
Therefore, the correct answer is not listed. The surface area of the rectangular prism is 162 square inches.
