To find the surface area of a box, we need to calculate the area of each of the six sides and then add them together.
The formula for surface area of a box is:
Surface Area = 2lw + 2lh + 2wh
Given that the box is 8 inches by 4 inches by 3 inches, we can plug these values into the formula:
Surface Area = 2(8)(4) + 2(8)(3) + 2(4)(3)
Surface Area = 64 + 48 + 24
Surface Area = 136
Therefore, the surface area of a box that is 8 inches by 4 inches by 3 inches is 136 square inches.
what is the surface area of a box that is 8 in by 4 in by 3 in?
