Cubic feet and gallons 
20071119 

From Leonard: Every conversion I find to convert a cubic foot to a gallon is in liquid.
Question, how would 1 cubic foot convert to gallons in dry measurement?
Example say you have 1 Gallon of packing peanuts how many cubic feet would that be?
I can do this and have done it for the heck of it, I took a box 12x12x12 inches, which is a cubic foot,
filled it with packing peanuts the tried to fill a 1 Gallon container, that amount almost fills a 1 gallon
bucket twice.
I even ask a math teacher and was told that 1 cubic foot equaled 7.481 gallons,
then I said that is liquid, teacher ansered yes, then i ask what about dry and got
a response of I do not know. Answered by Harley Weston.
