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.
