Yes, I appreciate that, but it still seems to me that 3D-Tetris has some 
similarities with what you're trying to do in that the shape and its 
orientation matters when you're filling a container. Calculating how to 
fill a container with a mix of sofas, chairs and desks springs to mind. 

Obviously, the people doing the stacking manually optimise container 
packing, but maybe your loading calculator should as well, otherwise it 
may miscalculate the amount of stuff it include in a load. 

It may not matter so much if it underestimates a load, but is it likely 
to cause problems if it consistently overestimates what can be put in a 
container?
