I'm going to cut this in half for safety reasons, and if my maths is correct weightwise 900 mice seems feasible, but I don't know if they will be in good shape at that concentration. A few casualties are okay, but ultimately these hypothetical mice are supposed to mostly get to their destination alive. (it's a short trip, incidentally, two hours tops, so I'm not worrying about food or recreational activities for these mice.)
(All numbers are rounded because I am lazy)
This turned out to be educational. This is more feasible than I thought weightwise, but I'm still not sure if these mice can survive at that concentration.
That number is not feasible because a great majority might suffocate. Have in mind that, the more uncomfortable they feel, the more stressed might become and, in extreme cases, even violent. So you can end up with a scenario where they start killing each other as they fight to remain on top of the pile and not suffocate. If they are intended to be kept alive, choose a number under 50. The volume for the animals' survival will be meassured horizontally, not cubically. Whatever space you want to add vertically will be to give them some sense of freedom. Remember they are live animals and they have to move around to not fall into a panic induced, fight-or-flight state of madness.
However, no matter how strong a person is, the box's volume will have the limits of the person's arms reach, and the fact that you can't carry a package over a certain size without tripping because you can't see.
