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

Answer 1

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

The formula to find the surface area of a rectangular prism is:

Surface area = 2lw + 2lh + 2wh

Given the dimensions of the box:
Length = 12.5 inches
Height = 9.5 inches
Width = 3.0 inches

Substitute the values into the formula:

Surface area = 2(12.5*9.5) + 2(12.5*3.0) + 2(9.5*3.0)

Surface area = 2(118.75) + 2(37.5) + 2(28.5)

Surface area = 237.5 + 75 + 57 = 369.5 square inches

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