To find the surface area of the box, we need to calculate the area of each of its six faces and then add them all together.
The net of the box would look like this:
L = 12.5 inches
H = 9.5 inches
W = 3.0 inches
Front and back faces: 12.5 inches (L) x 9.5 inches (H) = 118.75 square inches (each face)
Top and bottom faces: 12.5 inches (L) x 3.0 inches (W) = 37.5 square inches (each face)
Side faces: 9.5 inches (H) x 3.0 inches (W) = 28.5 square inches (each face)
Now, add up the areas of all six faces:
2(118.75) + 2(37.5) + 2(28.5) = 237.5 + 75 + 57 = 369.5 square inches
Therefore, the surface area of the box is 369.5 square inches.
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?
