Figured this would be appropriate here

How do you calculate the gallons of an aquarium if you only have the measurements? thank you very much in advance

Go to www.glasscages.com

That way you can match up the size of your tank to that, and guesstimate.

awesome so i have 2 custom almost 70 gallon hex tanks with radiant heat panels sitting in my moms garage

L x W x H is accurate for most rectangular tanks, but for a hexagonal tank you will have to calculate for the volume of a hexagonal prism (a shape with a hexagonal top and bottom, and six rectangular sides). It's sort of complex, but it's basically 3 x a x s x h = Ah, where a = apothem length, s = side, h = height. If you can give some dimensions I can figure it out for you.

edit:: apothem is the distance from the center of the base to the middle of one of the side panels (NOT the corner), basically like the radius of a circle. You can measure across the top of the tank from the center of one flat side to the opposite one, and divide by 2 to find it.

i'll measure it tomorrow and post sometime in the afternoon yea sounds kinda complicated

You just need the apothem length, the length of one of the sides of the hexagon, and the height and I can tell you. It will be less than 70 gallons, since the formula was wrong.
