A 10x10 square can obviously hold 100 unit circles (diameter=1) when arranged in rows and columns. What is the maximum number of non-overlapping unit circles a 10x10 square can hold if the circles are packed closer together?

(In reply to another direction by Larry)

i also found myself thinking in terms of pennies, but the problem calls for CIRCLES.
