Question: 3D Bin Packing formulation

Hello

Long time asker of minimization problems here.

Following on from my question on 2D packing.

I found this "solved" problem for packing 3D items efficiently. See Illustration 6.13

Some discrepancies with constraint set-up (first one), number of variables and the optimized solution.
