can someone that is mathematically inclined help me please?!

ok so im (in-depth) designing a snake rack, i have an OCD about cutting before i measure. and this is what the outcome is from my own problem lmfao

i wanted to build a 28QT 10 tub rack, i didnt want to use anyone elses design cause well... idk... anyway! so my rack is designed using 3/4th" cabinet grade natural plywood(treated woods are poisonous for snakes apparently) and some other things that are easily handled on my own lol.

ok so here is my design so far. i need someone to check my math and design to make sure EVERYTHING is perfect before i buy the wood and cut it to size.

please do not reply saying (your over thinking things) or (why dont you just use something already made)

just please be mature :D thank you everyone!

P.S. i understand that these dimensions are impossible to get perfect using wood, a tape measure and a saw. i will round to closest possible dimensions though :D

P.S.S. i think im just going to be a pain and make HD cut all my wood ;) lol ill prolly get my wood and a letter to never come back haha

forget mesurements, the ones measuring hieght are useless, you only need to measure the internal dimension for the board length, then after you get the floor board on, stick a tub with the lid on it in there, then set a ruler on the left and right side of the tub, lay the board on top, mark, level, and drill. if you need to hold the thing together while doing all this, cut the sides about a foot taller then you nedd them and drill in a 2x4 on the front and one on the back (if it were standing up), and after you get your final floor board on, mark the top board, and before you drill it, take the whole thing and cut off what you dont need from the top.

but if you want to do it your way, then here goes, if the bottom floor sits between the two sides, then the sides will need to be 72.55, if it sits below the two sides, the sides will need to be 71.8, and since thats gonna be a b**** to measure, set it between them and give yourself a slightly less painfull headache:gj: good luck! i hope i helped

Math looks fine to me.

math is right

im still not understanding the subtracting half of the wood thickness, but that could be explained by what ever design you have planned. I don't see it though.

You may run in to issues trying to install each level with specific measurements like that. I did something similar while in the planning stages of my XPVC racks just to make sure my cuts weren't too short, and then I intentionally cut the legs 2 or 3 inches longer than needed. Attach the first piece to the bottom flushed with the ground and then work your way up. Like cmack said, add a tub with its lid on (to provide the gap), lay the next shelf on top of it, make it level, and screw it in. When you get to the top you should have a few extra inches of legs/supports left over. I flipped the racks over and used them as legs. You can also just cut them off.

BTW, I'm getting 71.8" for your two vertical supports, not 72.125. I'm not sure why you only subtracted half of the top shelf. If you do have a reason, it should be 72.175 not 72.125.

10x tubs @ 6.38 = 63.8
10x shelves (his top one is sitting on top) @ .75 = 7.5
10x gaps @ .125 = 1.25

72.55

Derp. Now I'm not sure why I was subtracting the top shelf either. :confused:
