For many paints, one gallon will cover 400 square feet. However, the quality of the paint can affect how much it will cover.
Anywhere from 300-500 square feet depending on the thickness/thinness of the paint, how many coats you're putting on from a single can, and how large the surface is you're painting. However, 300-500 square feet is an approximate average of how much a gallon of paint should cover.

To answer this question, you need to know how much a gallon or unit of the paint can cover and the price per gallon or unit of the paint. Let us say a gallon covers 120 sq ft and it costs 10 dollars a gallon. You would need 600/120 gallons, which is five gallons and it would cost 5 x 10 dollars, which is fifty dollars. This is just an example, not an estimate. The other cost would be labor if you hired someone to do it. Otherwise you would also have to add the cost of a paint roller and pan, and brushes if you did it yourself.
