1 cubic meter = 264.172 US Gallons, so 10 cubic meters = 2641.72 US Gallons
1.337 cubic feet in 10 US gallons.
ten gallons is about one and a third cubic feet, so I would say that 30 gallons is about 4 cubic feet
6 cubic meters
1,000,000 cubic feet or 6,229,000 gallons.
Assuming the pool is exactly circular... volume of pool = (pi x 5sq) x 3ft =235.619 cubic feet hence... 235.619 cubic feet = 1762.552 gallons (US) or 1467.631 gallons (UK)
10 x 10 x 10 = 1000 cubic meters.
10 gallons is 80 pints.
First figure out how many cubic inches are in your pipe. pi (5 in ) ^2 x (80 ft x 12 in / ft ) = 78.54 in^2 x 960 in= 75398.4 in^3 there are .4 us gallons in 100 cubic inches (75398.4 in^3 / 100 in^3 ) x 0.4 gal = 301.59 gallons
Ten.
I presume a mega-litre is 10^6 liters. By definition, a litre is 1000 cubic centimetres -- that's a cube ten cm on a side. You can see, then, that one cubic meter would hold one thousand litres. A thousand thousands make a million, so a megalitre would be the same as a thousand cubic meters.
10,000 meters
Volume = pi R2 L = pi (2)2 x 120 cubic inches / (231 cubic inches per gallon)The volume (capacity) of the pipe is 6.528gallons. (rounded)
