The surface area of a rectangular prism can be found by adding up the areas of all six sides.

The front and back sides have a length of 8 inches and a height of 12 inches, so the area of each of these sides is 8 inches * 12 inches = <<8*12=96>>96 square inches.

The top and bottom sides have a width of 2 inches and a length of 8 inches, so the area of each of these sides is 2 inches * 8 inches = <<2*8=16>>16 square inches.

The two side sides have a height of 12 inches and a width of 2 inches, so the area of each of these sides is 12 inches * 2 inches = <<12*2=24>>24 square inches.

Adding up all six sides, the surface area of the cereal box is 96 square inches + 96 square inches + 16 square inches + 16 square inches + 24 square inches + 24 square inches = 272 square inches. Answer: \boxed{272}.
