How Many Cubic Inches Is My Tank

[pcurry18]

First off, i failed math...lol....my tank is six sided tank. Each side is 14 inches. The height is 30 inches. the length across is 24 inches in any direction. i need to know the cubic inches in order to determine the exact gallonage. Any help would be greatly appreciated.

They quote

Surface Area = 374"
Volume = 63.61 UKgal

10,080 cubic inches based off of your measurements

edit...(I neglected to notice you said six-sided tank, lol)

It seems weird to me that is has more volume than a 50 gallon barrel does?

If you divide the hexagon into triangles and find the area of each triangle then multiply by 6 to find the area of the hexagon then multiply by the height that is the volume in cubic inches. So...

Area of a triangle=0.5base(height)

A=(0.5)(14)in(12in)=84in²

Area of the hexagon=84in²*6

A=504in²

Volume of a hexagonal prism=area of base*height

V=504in²*30in

V=15,120in³

Diagram:


15,120 (cubic inches) = 65.4545452 US gallons
15,120 (cubic inches) = 54.5022877 Imperial gallons

Your killin me...lmao..are you a math wiz or what...i would have never figured that out! grrrrrr...thanks though. that site is pretty kick ass too! thanks for all the inputs

are you a math wiz or what

I did just get an A- on the review test we had over geometry in math this last week. Also, based on your measurements I already knew it was a standard 65-gallon hex; I just wanted to show off my skillz.
