Okay first things first, I'm not a builder by any means, but give me the materials and instructions and I can pretty much follow them and get the job done.

Well I gotta find out how much material I am going to need to build my rack.
I'd like to get a 5 or 6 slot rack out of a 4' x 8' sheet of expanded PVC. So here was my method to my madness, is this correct?

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??

I made a drawing but basically the total dimensions of the rack will be 18.5"w x 31" h x 24"l

it should take 2 side pieces, 1 back piece, 2 kick panels(like on the bottom so the bottom rack isn't on the floor) and 6 drawer pieces(that includes the bottom and top)

thanks for any help!!! sorry if this is too crazy haha
