You can put this solution on YOUR website!
The internal diameter is 12mm, so the radius is 6mm = 0.6cm.
The length is 50m = 5000cm.
We can calculate the volume in cubic centimeters (practically the same as milliliters)
as the volume of a cylinder of radius r=6 , in cm,
and height h=5000 , in cm:
Volume+=+pi%2Ar%5E2%2Ah
Volume+=+pi%2A0.6%5E2%2A5000=pi%2A0.36%2A5000=5655 (rounded)
So the volume is about 5.7 liters.
5655+mL=5.655L
