i made a couple of boxes in the past, i know the 1728 equation but now i got to make a custom fiberglass enclosure but i don't know how do i get the correct volume inside. (it's an irregular shape)
is there another way to correctly mesure this.

thankyou for any help

sand,,, water,,,,styrofoam peanuts

so i actually have to make the enclosure first and then measure it with some liquid or sand then find a way to convert it to cubic inches.

styrofoam peanuts would be easiest to get a rough estimate....just fill up the enclosure and then measure how many peanuts you used... There is a conversion but I cant remember right now.. YOU could make a cardboard box that is 1 cubic foot and just use that to measure how much styrofoam you have..

You may not have to make the actual enclosure if you can mock-up some cardboard in your trunk or anything else that you can fill up as Pirate400 said. Also depends on how exact you really want to be - sand will be more accurate than styro peanuts, but prob doesn't matter to be that exact.

If you want to be really accurate, use water! 7.5 gallons = 1 cu ft.

Just be sure to double up on the plastic lining- the 6 gallons you see here would not be fun to siphon out!

water seems to be the best way since my system will be in my wheel well.
my buddy had a custom shop and he had this program that he use to use to make banpass and ported boxes, heve you guys ever heard about this.

and also 7.5 gallons = 1cubic foot......................................right
