If I recall, its L x W x H divided by 1728 = cubic feet

 

If your enclosure is not pefectly rectangular or square forget the math formulas.

Do this, get enough small plastic beads (any craft floral place will have this) to fill your sub box and fill it exactly to the max. Don't forget to put your woofer in the box to account for the displacement of the magnet.

Now carefully pour all those small beads into a shoe box or other rectangular box that you CAN measure. Now you can use your LxWxH measurement and you are done

We use this method for most of our round or "Tub" type fiberglass boxes and it is very accurate.
