Volume of custom boxes?

[ithaca00]

How do you go about finding the volume of odd-shaped boxes (i.e. tire wells, nooks&crannies, etc.)?

We have test equipment here that can test the box volume by measuring the resistance of the sub out of the enclosure vs. in the enclosure.

Before we knew we had that ability, we would use styrofoam packing peanuts and stuff the box with them. Then we would empty them into a square box that we could measure. It's not dead on but it's pretty accurate.

How ould you go about measuring the volume of the area before building an enclosure? I guess just use the peanuts.

Thanks for the help.

We measure the area as square as we can to make sure we have enough space. You can shrink an enclosure easier than enlarging it.

That packing peanuts thing is a pretty good idea...we have enough of those laying around the shop everywhere that's for sure

Sand works real well, and is very accurate. Of course you need a shape to pour it into. Once you've poured it, then empty it into a measuring container. If the container is measured in liters or milliliters, then convert the figure into cu feet.
