answered-by-expert Expert Answer
Density = mass / volume.
 
mass of the given rock piece is measured using physical balance.
 
Let us take a measuring jar and fill water in it partially. 
 
By immersing the given rock piece in measuring jar using a piece of thread,  we can measure the displaced volume of water.
This displaced volume is the volume of given piece of rock.
 
By knowing mass and volume, we can  calculate its density
