How many liters of diesel can a cylindrical iron drum with a height of 0.9 meters, a diameter of 0.6 meters and a circumference of 1.8 meters hold?
Height H=9dm, diameter D=6dm, and the circumference is redundant (and should be slightly larger than1.8m); The volume of the oil drum is π h (d/2) 2 = 3.142 * 9 * (6/2) 2dm3 = 254.502l, but in fact, considering the wall thickness of the oil drum itself and the tension of the liquid, the maximum diesel load should be about 254L.
