The information on a one-gallon paint can is that the coverage, when properly applied, is 450 ft sq. One gallon is 231 cubic inches. What is the avg. thickness of the paint in such an application?

Please explain how to do this. The answer should be in inches.

    Paint thickness multiplied by area covered should equal the volume of paint.
    Let T = thickness of paint.
    T = (volume of paint) / (area covered)
    T = (231 in^3) / (450 ft^2)

    Convert 450 ft^2 to its equivalent in in^2, divide, and you have the answer in inches.
