for you mathmaticians

well heres one i should know..

if a tank is

30 in. Long
12 in. tall
12 in. deep

how many gallons is it?

i swear i could have done this at some point... but any help is appreciated... measurements might be the slightest bit rough but are almost spot on... thanks

Just multiply the length, width and height by centimeters and then divide by 1000. Answer is in liters. You can divide the answer by how many liters per gallon.

18.7 Gallons

Heres a site ive been using for a while now to find out gallons/dimensions: Link
And yours is 20gallons

L x W x H then divide by 231

That is the standard size for a 20 gallon long tank ...but doing the math comes out to 18.7 gallons which takes in account for the thickness of the glass

I knew it was there.... but it is good to know a way to do it if you are out and run across a used tank and need to know the size.
