Hi, I have to do a math project for school. For the project I have to come up with the costs of renovating a house. I have to put in tiles, wall paper, parquet flooring, etc. as well as get some paint. Basically, I need to find a website that has the prices for these items. I tried HomeDepot.com, and that was not helpful at all. Well, thanks for the help. EDIT: Plus, I have a question. How many square feet does a gallon of paint cover?
