20 x 20 is only two dimensions, like length and width, but no height, so it wouldn't be able hold any gallons. You have to add the height measurement, and then the measuring distance. Perhaps it is 20 x 20 x 5, but is that inches or feet or cm? The measuring distance is needed to calculate how large the container is.
6-ft x 18-in x 20-in = 72 x 18 x 20 = 25,920 cubic inches = 112.208 gallons of space,regardless of what's in it. Even if it's empty.
