I got a new tank... but I dunno what size it is!

[Lymore]

I got some sort of flatback hex tank, stand, and light for $50, woooo.

I was told its 29 gal... but I can't find anything about a 29 gal flatback hex... I was wondering, could it actually be 33 gal?

Or do 29 gal flatbacks exist?

What are the dimensions?

 

[Lymore]

I've been looking for some sort of measuring device since I posted this... I can't even find a ruler

Maybe my bf has a tape measure somewhere....

It could be a 33....a friend of mine had a 33 flatback hexagon tank about 20 years ago. I have no idea what the dimensions were but it was probably about 36" long, 12" wide and maybe 18-20" high.

Okay, here we go, my bf's brother found a tape measure (my hero lol):

The back side of it is 3ft

The front side is 10.5 in

The diagonal parts on the front are both 8.5 in

and the sides are both 7.25 in

 

[Lymore]

Oh yea, and its 21 inches high


does a 29 gal flatback hex even exist? I haven't been able to find anything online.

 

[Lymore]

oh, and the thickest part (from front to back) is a little over 12.5 in

 

[Lymore]

lol, theres so many sides to measure!! Its not like a simple rectangular tank, with height, length and width

 

[Zagz]

It may be a 26 gallon. I couldn't find an accurate calculator for flatback hex's LOL. There is a lot of information on the 26 gal.

 

[Lymore]

I found an aquarium calculator for rectangular aquariums, and if the front just straight across it says it would be 40.91 gal

OK, I'll do the math:

It is actually not that difficult to calculate.

The foot print of the tank is:
(width x depth) - 2 triangular areas < And Area of the 2 triangles = [2 x 1/2 x] (depth - sides) x (width at back - width at front)/2 >

36 x 12.5 - (12.5-7.25)x(36-10.5)/2 = 450-67 = 383 sq in.

Volume is footprint x height:

383 x 21 = 8043 cu in = 34.8 gallons.

If you measured the outside of the tank, you will have to subtract the thickness of the glass & the gap at the bottom of the tank ... so it could be a 29.

Ohh yea, geometry. Lol... I only graduated last year, and I'm forgetting already.

 

[jsoong]

See, things they taught you in school do come in handy sometimes!

 

[Lymore]

lol, I never doubted that some things were useful, I just forget too easy.
