... Here's my math.

In my example I wrote that the chips would be "placed flat and lined up edge to edge." Do this with four (4) chips to form a square of sorts. The space in the middle of the four chips looks kind of like a curved diamond. The term for this is interstitial space. In my example I kept the interstitial space.

A football field is 100 yards long (300') with a 10 yard (30') end zone on each end. The total length is 360', or 4320". A chip is 1 9/16" (1.5625") in diameter. 4320 divided by 1.5625 = 2765 chips.

A football field is 50 yards wide (150'). This is 1800" divided by 1.5625" = 1152 chips.

1152chips X 2765 chips = 3,185,280 chips.

OK, I just reviewed my post. I'm off by 1152 chips. I must have rounded up when I should have rounded down. That is exactly the number of chips in one chip-line along the width. See what happens when you do this without adult supervision?

What do you think?

I think we're BOTH nuts!
