How to calculate the weight of iron Known diameter is 32 mm! Length is 300 mm! Find its weight! The result is converted to kg! It is a solid iron cylinder!
First you know the density of iron, and then you multiply the density by the volume
Obviously, this iron is a cylinder with a bottom radius of 16mm and a length of 300mm
The volume of tapping v = pi * 16 * 16 * 300
Then multiply by density
Pay attention to the conversion of units
