How many UPBs could you fit in a briefcase? I'm working on subplots and the idea of a small heist came to mind. And considering a UPB is about the size of a grain of rice, I was wondering how big of a hall an entire suitcase full of them would be. I really, really don't like the idea of having to figure out, by volume, How many grains of rice could fit in a briefcase, so I was hoping someone else may have already done it.

So... Has anybody already done the math, or am I in for a whole lot of number crunching today?
