Take the dimensions in inches, multiply them.
Whatever the big number you get, divide by 231 (the number of cubic inches
in a gallon).

I did that, got 34.9 gal.

I'm trying to figure out how many gallons a tank will hold. I've tried
googling with no help. The tank is 28" x 18" x 16" and it's supposed to
hold 35 gallons. It just seems too small to me. In comparison I have a
tank that measures 13" x 12" x 18" and I'm sure it only holds around 12
gallons. Any help is appreciated.
