11(11)(2) ft^3 X 7.48 gal/ft^3 = 1810.16 gal
20 ft * 10 ft * 4 ft = 800 ft^3 1 ft^3 = 7.48052 gal 800 ft^3 * 7.48052 gal/ft^3 = 5,984.4 gal
The volume is that of a cylinder: radius = ½ × diameter volume = π × redius² × height = π × (½ × 3)² × 5 ft³ = 11¼π ft³ ≈ 35.343 ft³ What this is in gallons depends upon the gallon used: 1 ft³ ≈ 6.229 imp gal → 35.343 ft³ ≈ 35.343 × 6.229 imp gal ≈ 220.15 imp gal 1 ft³ ≈ 7.481 US gal → 35.343 ft³ ≈ 35.343 × 7.481 US gal ≈ 264.38 US gal
.1337 cu ft / gal 7.481 gal / cu ft
The pond is a cylinder; radius = ½ × diameter volume_cylinder = π × radius² × height → volume_pond = π × (½ × 5 ft)² × 1 ft = 25π/4 ft³ ≈ 19.63 ft³ Converting this to gallons depends where you are: * In UK: 1 ft³ ≈ 6.23 imp gal → 19.63 ft³ ≈ 19.63 × 6.23 imp gal ≈ 122.3 imp gal * In USA: 1 ft³ ≈ 7.48 US gal → 19.63 ft³ ≈ 19.63 × 7.48 US gal ≈ 146.9 US gal (Other countries probably use the same as the UK: the imperial gallon.)
1 cu ft ≈ 6.22884 imp gal ≈ 7.48052 US gal 12 in = 1 ft → 7'4'' = 7+4/12 ft = 7⅓ ft → volume = (6 ft)² × 7⅓ ft = 264 cu ft ≈ 264 × 6.22884 imp gal ≈ 1644 imperial gallons ≈ 264 × 7.48052 US gal ≈ 1975 US gallons
965.46 Imp gall
At are 7.5 Gal per Ft3
1 cu ft ≈ 6.22884 imp gal → 72 million cu ft ≈ 72 million × 6.22884 imp gal ≈ 448.5 imperial gallons 1 cu ft ≈ 7.48052 US gal → 72 million cu ft ≈ 72 million × 7.48052 U gal ≈ 538.6 US gallons
1 cu ft ≈ 6.22884 imp gal ≈ 7.48052 US gal 12 in = 1 ft → 7'4'' = 7+4/12 ft = 7⅓ ft → volume = area base × height = π × (6 ft ÷ 2)² × 7⅓ ft = 66π cu ft ≈ 66π × 6.22884 imp gal ≈ 1292 imperial gallons ≈ 66π × 7.48052 US gal ≈ 1551 US gallons
7 ft x 2 ft x 2 ft = 28 cu ft 1 cu ft = 7.48052 gal 1 cu ft = 28.3168 L So, the volume of the aquarium is: 209.455 gal = 792.872 L
aprox 400 gal i have a 4 ft dia tank that's 6 ft long it holds 200 gal
