mass = volume x density. The units, of course, have to be compatible - for example, if the volume is in cubic meters, and the density in kilograms per cubic meter, the mass will naturally be in kilograms.

mass= density*volume
Density = Mass/Volume so Mass = Density*Volume.
calculate the volume using the formula: Vsphere = (4/3)*pi*r^3 then calculate density by Density = Mass/Volume
Density of a substance = (mass of a sample of the substance) divided by (volume of the same sample)
You cannot calculate the volume of an object using only the density; you must also calculate the mass.You can calculate the mass by simply weighing the object.Density = Mass / VolumeTherefore Volume = Mass/Density.If you cannot be bothered to calculate the mass, simply measure the object. Multiply the length, times the width, times the height and you have the volume.
