Evil trick questions, perhaps?

I wrote this one a while back out of boredom:

Assume that you have an amount of perfectly spherical containers with the radius 96.8 vendekometers, and your Physics' teacher want you to find out how many of these spheres it would take to hold (or contain) exactly 548.47169 xennalitres of Einsteinium in plasma form. How many whole atoms can you get into containers, and what is the amount of containers neccesary for this process? Write the answer in binary form.

---

The answer is 0, because the containers are too small to fit a "whole" atom.

Actually, that one was a bit too complex for a D2 contest, but you might get the idea.
