Take 48" X 18" X 18" = 15,552 cubic inches
divide by 1729 to get cubic feet
(12 X 12 X 12 = 1729 cubic inches in a cubic foot)
Convert to cubie feet = 9
7 . 480 gal per cubic foot
9 X 7.480 = 67.32 gal tank

You know if the 67.32 is the gallons figured, the inside dimention may be slightly smaller. It may be an even 65 gallon tank. Lesley

Gerrrrr.
You had to make me curious didn't ya.
Measured the outside (including plastic frame) of a 55 gal.
48.25 X 12.75 X 20.75 = 12765.14 cu. in
or 7.3872 cu. ft. X 7.48 = 55.2565 gal
Hmmm..... you don't fill it to the very top, and the outside dimentions of the moldings are much wider than the inside dimentions.
We are all getting ripped off. :notsure:
