**MathMate**, Tuesday, February 22, 2011 at 11:53amAssuming a jar of (10cm)³.

Then a crude estimate is to line them up in all three directions:

(10/2)*(10/1.5)*(10/1.5)

=5*6.7*6.7

=225

Note that I have used a fractional number of beans because we don't really line them up perfectly. They will be crossed. Also, the space between two layers could be better used by placing a jellybean in the depression between two beans of the lower layer. This can be automatically done by shaking the jar after it's been filled.

See what others give, hopefully a more refined estimate.
