Density is a measurement of how solid something is. Specifically it is the mass per unit volume of a substance. If you have two objects of the exact same size (volume), the more dense object will weigh more than the less dense object. So there are two things contributing to density:
What Is The Definition Of Density? Basically, density is how compact an object is. Put another way, density is the mass of an object divided by its volume. Weâll find out about mass and volume below. How Do You Find Density? In order to find out the density of an object, you need to know two other things about the object: its volume, and its mass. You would then divide the mass of the object by its volume to find its density. Volume
