How many gallons is this octagon?

[Day13]

So with the new info Apothem is 9" because center to middle of the side is 18" cut in half. Then 25" height with roughly 10" sides puts my volume at 6750 divided by 231 makes it a 29 gallon tank? Thanks

How many panes of glass are there?

Mine has maybe 3-4 inch sides. If your sides are 10 inches long then it's WAY bigger than a 35.

Ok exactly 6 sides, so a hex, my mistake on the octa. each pane 25" tall 10" wide, measures 21" from one corner to another, 18" across (middle of 1 side to another)

Okay just checked downstairs...IDK what I was thinking about me saying mine are 4 in.

Their more like 10 like you said.

My GF calculated it...it's a 38.8 from the outside dimensions. Obviously the inside would be shorter so mine IS a 35 hex. The sides are a foot long and it is 24 inches tall.

By doing your dimensions it's 28.1 gallons. So a 25 hex would make sense. That was way too hard, lol.
