Ok, sooo a lady down the street had her garage door open, I saw a tank, asked her what she was doin with it.... she told me to take it..... so i did! when I got home I measured the bad boy because I had no idea what it was.... it looks like two 55gal stacked on top of eachother. and it pretty much measures the same... I even googled the measurments to find this tank and cant.... need help! HOW BIG IS MY NEW TANK???! I mean, HOW MANY GALLONS??!?!

48" Long x 13" deep x 31" height! its a tall mother!! soooo anyway, because its perfectly the same as my 55gal in length and depth (well 1/2" off on depth), I am using the stand and hood I have.... and I get a bigger tank... sweeeeeeet deal... but i want to know how many gallons it is.... someone HELP ME!

L(inches)xW(inches)xH(inches) x.004329


48x13x30 x.004329= approx. 81 gal, if your dimensions are not inside dims. then this is probably an 80 high


dimensions should be taken from inside the tank, and the actual multiplier is .00432900433

Do the math You provided measurements in inches im assuming:
Width: 48" (121.92cm)
Height: 31" (78.74cm)
Depth: 13" (33.02cm)
Your tank's volume is approximately 19,344.0 cubic inches or 83.7 U.S. gallons, which is approximately 325.7 liters.

lol, I was more of an algebra guy... hated geometry... thanks guys.

Length x width x hight ÷ 231 =?

1 divided by 231 = .004329 lol

LoL...Fish and Math Nerds.....
