None, since there can be no conversion. A foot is a measure of length in 1-dimensional space while a gallon is a measure of volume in 3-dimensional space. The two measure different characteristics and, according to the most basic principles of dimensional analysis, any attempt at comparisons or conversions between the two are fundamentally flawed.
5 ft 6 in = 167.64 centimeters
A 5-gallon container can hold 640 fluid ounces of water.
Fill the 5 gallon can completely. Then pour the water from the 5 gallon can into the 3 gallon can until it's full, leaving 2 gallons in the 5 gallon can. Next, empty the 3 gallon can and pour the remaining 2 gallons from the 5 gallon can into it. Finally, fill the 5 gallon can and pour water into the 3 gallon can until it's full, which removes 1 gallon from the 5 gallon can. This leaves exactly 4 gallons in the 5 gallon can.
5 ft 0 in is equivalent to 152.4 cm.
The conversion from feet to centimeters is 1 ft = 30.48 cm. Therefore, 5 ft 8.5 is approximately 173.99 cm.
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
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.)
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
