Firstly, we need the voulme of that pipe, which is going to need us to settle on a common unit. I prefer metric, and you need a metric answer anyway, so 3" is 7.62 cm. 800 m is, of course, 80,000 cm.
Volume of a cylinder is the area of its face multiplied by its length. Area of a circle is Pi multiplied by the radius squared.
The diameter is 7.62 cm, so the radius is 3.81 cm (half the diameter). Squared this is 14.5161 cm2, multiplied by Pi is approximately 45.6 cm2.
Volume is therefore 45.6 x 80,000 = 3,648,000 cm3.
Generally speaking, 1 litre is the same as 1000 cubic centimetres (although technically it depends on the susbstance, pressure and temperature too, but let's not get silly).
So, 3,648,000 cm3 = 3648 l.
Just out of interest, assuming the pipe contains water, the mass of the water will be 3648 kg, since one litre of water weighs one kilo(gramme).
There are nine liters in 0.009 cubic meters.
50 liters is 0.05 cubic meters.* Liters x 0.001 = cubic meters
Liters can't be converted to meters. Liters measure volume, while meters measure length.

1.111 cubic meters equates to 1111 liters. * cubic meters x 1,000 = liters
48 cubic meters is 48,000 liters.
meters is a measurement of length, liters is a is a measure of liquid. There is no answer
.46 cubic meters is 460 liters
0.75 liters = 0.00075 cubic meters.
There are 32,000 liters in 32 cubic meters.
0.78 cubic meters is 780 liters.
1 inch=0.0254 meters
