A shipping box has a length of 12.5 inches, a height of 9.5 inches, and a width of 3.0 inches. What is the surface area of the box?

1 answer

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

1. Front and back sides:
- Area = length x height
- Front side: 12.5 inches x 9.5 inches = 118.75 square inches
- Back side: 12.5 inches x 9.5 inches = 118.75 square inches

2. Top and bottom sides:
- Area = length x width
- Top side: 12.5 inches x 3.0 inches = 37.5 square inches
- Bottom side: 12.5 inches x 3.0 inches = 37.5 square inches

3. Side sides (left and right):
- Area = height x width
- Left side: 9.5 inches x 3.0 inches = 28.5 square inches
- Right side: 9.5 inches x 3.0 inches = 28.5 square inches

Total surface area = Front + Back + Top + Bottom + Left + Right
= 118.75 + 118.75 + 37.5 + 37.5 + 28.5 + 28.5
= 369.5 square inches

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