I reckon the main structural strength from a holographic 3D POV is the cast chassis spaceframe, handling torsion / tension the lot
creating the equivalent of rigid I-beams in the bottom plane surrounding all four of the pack-frame edges.
Therefore that frame together with the cells is simple rectangular prism / slab, acting as a floor alone
load-bearing the seats, passengers and other contents sitting on that floor
with of course a role to some extent locking in and supporting that frame at those four edges adding rigidity.
The honeycomb slab replacing trad crossbeams in that function.
That slab would be much LESS strong without the cells.
As opposed to a much heavier / cruder trad floor structure that would need to be just as strong with or without the modules is is designed to support
and whose load bearing capacity would be GREATER without them.
