511 square inches

To find the surface area of the box, we need to find the area of each of the six sides and then add them up.

Top and bottom: 12.5 inches x 3.0 inches = 37.5 square inches x 2 = 75 square inches
Front and back: 12.5 inches x 9.5 inches = 118.75 square inches x 2 = 237.5 square inches
Sides: 9.5 inches x 3.0 inches = 28.5 square inches x 2 = 57 square inches

Now add all the areas together:
75 + 237.5 + 57 = 369.5 square inches

Therefore, the surface area of the box is 369.5 square inches.
