I read the instructions on the bag of Quickcrete (60 lb.) I bought, and
it says to use 4 quarts of water with it, maximum 5 quarts. There's no
mention of how many cubic feet (or inches, I figure a cubic foot is 1725
cubic inches) I can expect to get out of a 60 lb. bag. I don't want to
mix much more than I'll need, and figure a sure don't want to mix less.
How do I determine how much to mix?

A 60-lb bag will make just under 0.5 cu-ft, an 80 about 0.6. *It's
printed on the bags somewhere, I'm sure.
