I'm fitting out a Igloo ColdMax 100 Quart cooler to take a Corny Keg on the road. As I was playing with the interior dimensions of the cooler (31.5inx13.5inx11in[LxWxH]), giving me 81 quarts of useable volume.
Wanting to know the total volume occupied by the Corny, I plugged in common dimensions:
4.5^2*23 = 8 quarts = 4 gallons
Yet the specs on the Corny call it 5 gal capacity.
If the outside of the keg occupies only 4 gallons of volume, but the inside of the keg can hold 5 gallons of volume, is there an interdimensional component to the keg?
I've checked it over a few times. Did I make a mistake somewhere?
