This might take a while.

It's common cents.

Oh, yeah: Thanks classicman.

I couldn't get your original image to copy as an image. It says it's a part of a video.

Hey Kerosene - Does that father in the pic look like anyone you know?

Probably not to you, but I did a double-take when I first saw it on my news feed.

Another fun fact, math nerds please verify....
I read that the cost per sq ft. was $2.58 in pennies.
GO!

The diameter of a US penny is 0.750 inches, so it's area is 0.4415 sq in.
A 1x1 ft square has an area of 144 sq in.

The pattern for maximum packing of US pennies in a 1x1 ft square
is left as a simple mind-exercise for the Reader... :rolleyes:

Is there a simple equation that can be used to show how many circles of radius (r)
can be packed into the rectangle (l x w), in the optimal way? So that no circles overlap.
(r is less than both l and w).

...And it seems the answer is "we don't really know" :)

I would ask why you insist on packing a square foot of pennies in a shape that is a square? To my mind, a square foot of pennies could be much more reasonably accommodated in a hexagon.

Lamplighter 06-26-2012 10:44 AM

because your parents were honeybees ?

BigV 06-26-2012 10:46 AM

because circles pack well in hexagons

Squashing my buzz. :mad:

I want a DIY guide. How do you seal those down? We have wood laminate floors now, could you do it on top of that?
