Pictures of custom boxes

I've got a lot of different custom enclosures I've done on my website.  Here's the link: http://www.sounddomain.com/memberpage/304268

Here's a picture of the nearly finished enclosure I built for the Porsche 928 on the last page:

How and the heck do you calculated volume for curved enclosures like that? I am great at  algebra but not  geometry so maybe that's why I can't fathom that whole concept.

I just get an idea of the area I'm working with and figure from there.  They usually come fairly close, close enough to not really matter.  As an example, the above was figured at 1.4 cubic feet.  When I actually measured it with water, it turned out to be 1.49 cubic feet.  I think people put too much emphasis on enclosure size precision when in fact the audible tolerances are quite large.
