How many gallons of water in one cubic foot of ice?

Answer 1

7.6

Answer 2

Slightly more than one cubic foot of ice, because water in its solid phase takes up more space than water in its liquid phase. To have a perfectly correct answer, it would depend on the temperature - water is the most dense at 4 degrees Celcius. Short version, ice expands due to the way the molecules of water arrange themselves in a very regular pattern in ice - water molecules can "slop past" each other, and thus can occupy less space.

Answer 3

That is approximately 7.48 US gallons
