Hexagon Aquarium Volume Aquarium Size (US Gallons) = ((3 x √3 / 2 x Length of One Side2 in Inch) x Height in Inch) / 231 In UK Gallons = s x 0.833 In Litres = s x 3.785 Where, s = Aquarium Size (In US gallons)


A fish tank with length 10 m, height 7 m will have a volume of
volume = ((3 x √3 / 2 x 102) x 7
volume = 7.873 gallons

In UK gallons ,
volume = 7.873 x 0.833
volume = 6.5582

In Litres,
Volume = 7.873 x 3.785
