**Reiny**, Monday, January 10, 2011 at 7:18pmdraw a picture of the floor, which is the 4 by 8 sheet of plywood.

The way I read your problem he needs 3 pieces of 8 footers of the 2by4's, two along the sides and one down the middle, and another 2 pieces of 4 feet of the 2by4's for the width.

so he will need 4 pieces of the 8 ft lengths.
