Cheerleaders Causing Trouble

Although in this case, not the trouble you might expect. Apparently, the girls at cheer camp, having already resolved the 10-dimensional sphere packing problem, decided to attempt a higher level of math by determining packing densities of non-uniform (albeit uniformed) shapes into a cube. How many cheerleaders can you stuff into an elevator? Apparently the answer is 25.

What remains untold is how the elevator repairman explained the smirk on his face to his wife after returning from the after-hours service call.
