Subject: how many coins?


Does anyone have a proof to the following:

Given a rectangular region of 2cm by 1000cm. You can fit 2011 (I think
it was 2011. It is more than 2000) coins of 1cm diameter in this region.

On the surface, it appears that the answer should be 2000, but someone at
the Bell Lab apparently proved that you can fit more (which, by the way,
is very significant for communication folks since each "coin" can be a
fiberoptic cable in an underground cable cases).
