If it's a cube shape it's just length x width x height in whatever unit of measurement you need for the tech spec you've got...
So if it is cubic centimetres and your box is 20cm x 20cm x 30cm your box volume is 12,000 cubic centimetres or 0.012 cubic metres.
And I seem to recall that if you fill the box with wadding of some description you can virtually increase the volume of the box - so the sub thinks the box is bigger than it is.
