Well true, but on the gripping hand, if you wanted to keep everyone alive (briefly) you would need to have at least 6 inches headroom, and perhaps a 2 foot by 2 foot by 6 foot rectangle for each person. Leaving an extra foot at the top per segment for structure (assuming the 2 foot width gives space for vertical support members).... Well, you'd be looking at a cube slightly larger than a mile in each direction.
