Basic Rack Building Questions

Can I calculate how much square feet a 4' x 8' sheet has? (answer is 32 sq ft right?) Then calculate the square feet of all my pieces (total is 31.7792 sq ft)

So then if that is correct that 4' x 8' sheet should be enough correct??

Theoretically, yes. Practically, no. You rarely ever can make the most use out of your pieces. For example some cuts you make from the sheet will not leave enough material on the uncut side to make another piece. It looks like you've thought it out pretty well though. If you are really worried about making the most out of your material, you can find a little floor space, lay your 4'x8' pattern on the floor in masking tape and use the masking tape to tape off the cuts you will make. That way, you can plan out your cuts better without wasting anything or redesign your plans to use only one piece.
