Hi

Sorry i know i've asked before but what are the dimentions of a 20 gallon tank in inches and how do you work this out?

Thank you.

20 long or high?

Aquarium dimensions - reference

I use this page when working out dimensions from gallons:-

Easy.

In inches, multiply the Length, Depth, and Height and divide by 231.

For example.

36" L x 18" H x 15" D = 9720 cubed.

9720 divided by 231 = 42.07 gallons.
