How do you account for this dependence in terms of Heisenberg uncertainty principle?"... To me this makes no sense because I see that HUP: dEdt = dxdp. I don't see an inverse relationship here, i see a direct relationship.
So, there's a few things you should look at here. The mention of the length, singular, of the box suggests that you're looking at a one dimensional system. The mention of the box, singular, suggests that you must be looking at a 1-box system. That'll be a model that you've probably studied specifically, so look at your notes for that particular model.
