To find the surface area of a rectangular prism, we need to calculate the area of all six faces and then add them together.
The two faces with dimensions 8 inches by 12 inches will have an area of 8 * 12 = 96 square inches each.
The two faces with dimensions 8 inches by 2 inches will have an area of 8 * 2 = 16 square inches each.
The two faces with dimensions 12 inches by 2 inches will have an area of 12 * 2 = 24 square inches each.
Adding up all six face areas: 96 + 96 + 16 + 16 + 24 + 24 = 272 square inches.
Therefore, the surface area of the cereal box is 272 square inches.
