To calculate the surface area of the box, you need to find the area of each of its six sides and then add them together.
1. Front and back faces: 12.5 inches x 9.5 inches = 118.75 square inches (x2 for both sides)
2. Top and bottom faces: 12.5 inches x 3.0 inches = 37.5 square inches (x2 for both sides)
3. Side faces: 9.5 inches x 3.0 inches = 28.5 square inches (x2 for both sides)
Total surface area = 2(118.75) + 2(37.5) + 2(28.5) = 237.5 + 75 + 57 = 369.5 square inches
Therefore, the correct answer is C- 369.5 square inches.
