fiberglass enclosure space calculations

[Tonyguy 10+ year member]

How do you determine the specs of a fiberglass enclosure when it is formed in a weird shape that isn't square? For ex., I want to build a fiberglass enclosure in the rear corner of my trunk. I want it to look like it was there from the factory. How do i determine the interior volume of such a weird shaped enclosure? //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

Fill it with water, or sand, or packing peanuts, or babies, whatever you have around, then measure that out.

Construct the enclosure, or a carboard mockup of what it will be and fill it with packing peanuts or another cheap/light material. Make a one cube box out of cardboard and see how many peanuts equals a single cube, and figure out how many peanuts you used during the mockup.

A little math can make everyone happy!
