Let's calculate cubic feet first, then convert to gallons. Volume=pir2h=3.14159x0.252x3=0.59 cubic feet 0.59 cubic feetx7.48 gallons/cubic foot=4.4 gallons
Easy. One cubic foot is equal to 7.481 gallons. So, just multiply cubic feet by 7.481 to calculate gallons.
If you remember the following facts, you'll never go wrong: ==> 1 cubic foot = 1,728 cubic inches ==> 231 cubic inches = 1 gallon
First calculate cubic feet: 3.1417 x Radius² x Depth = cubic feetNext calculate gallons: Cubic ft x 7.47 = gallons
Use this conversion: cubic feet x 7.4805 = gallons
There are approximately 224.71 gallons in 30 cubic feet.
1 US gallon = 0.133680556 Cubic Feet (ft3); and 1 day = 24 hours = 1,440 Minutes. Math equation for conversion where "x=number of gallons per day" is: (x / 1440) x 0.133680556 Example: If x=30 (gallons per day), then: 0.208333 x 0.133680556 = 2.785 ft3 per Minute.
Conversion: US gallons x 0.133681 = cubic feet
> Best work with cubic feet, first calculate the volume of the tank in cubic feet: = Length * width * height (all dimensions in feet) Then : For US gallons, multiply volume (cubic feet) by 7.4805 For UK gallons, multiply volume (cubic feet) by 6.2288
1 US gallon = 0.133680556 feet^3
Five gallons is 0.668 cubic feet.
Hi, multiply the L*B*W . that will give youvolume of any object , now if your result is in metre then 35.71 cubic feet in 1 cubic meter
