what is the surface area of a box that is 8 in by 2 in by 10 in?

Answer 1

To find the surface area of a box, you add the areas of all of its six sides.

The formula for the surface area of a rectangular prism (box) is:

Surface Area = 2lw + 2lh + 2wh

Given that the dimensions of the box are:
Length (l) = 8 inches
Width (w) = 2 inches
Height (h) = 10 inches

Plugging these values into the formula we have:

Surface Area = 2(8*2) + 2(8*10) + 2(2*10)
Surface Area = 2(16) + 2(80) + 2(20)
Surface Area = 32 + 160 + 40
Surface Area = 232 square inches

Therefore, the surface area of the box is 232 square inches.
