are you serious? you need 1 piece of plywood and 2 pieces of 1x2x8..... cut the plywood in half, you now have 2 pieces 2'x8' left, use one of those pieces and cut 2 pieces 3' long, you'll have a piece 2'x2' left over which can serve as a bottom shelf. nevermind.... if you cant figure out simple math i dont feel like typing anymore, thats a start for you, hopefully youll figure it out.
