You can also use the ProjectCalc Classic to determine
the total cost of a project, if you know the material’s cost
per unit. See the following example.

ing 15’ long x 12’ wide x 8’ high. If it costs $17.50 per
gallon, what is the total cost? First, multiply the perime-
ter of the room with the wall height, and then calculate
