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? Hint: Draw a net. (1 point)
A-511 square inches
B-341 square inches
C-369.5 square inches
D-184.75 square inches
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.
