What size is my tank?

Multiply length by height by width in inches. That gives you cubic inches.
Divide that figure by 1728 (the number of inches in a cubic foot) and that gives you cubic feet.
Multiply cubic feet by 7.48 (the number of gallons in a cubic foot) and that gives you gallons.
Example: My tank is 48" long, 18" high and 11" wide. (interior dimensions)
48 x 18 x11 = 9504 cubic inches
9504 ÷ 1728 = 5.5 cubic feet
5.5 x 7.48 = 41.14 gallons
Now all you need is a tape measure and a calculator (or pen and paper) and you can calculate the volume of any tank you come across.

I agree with Orion. While I have no doubt that sombunya's method will work, I prefer the following web site:
Quick Calculator for Aquariums
It has options for several tank sizes, which is cool. Just, fyi, it sounds like yours is 17.45 gallons, which means that Lotus' assessment is probably right on.

Yes, it probably is too much thinking, but not too hard to do if you understand the concept. Anyone interested in calculating fluoridation dosages?
(Just kidding. I'm actually quite lousy at math)
I looked at a used plexi-glass tank and quickly figured it to be an eighty gallon unit. Passed on it because it looked pretty scratched up.
