# Difference between Mass and volume

OK, I've googled it, I've tried to make sense of it, but I still have this one thing in my head that doesn't go away. Mass vs volume.

What is the difference between the two. If mass is the amount of matter,matter contains and volume is the space enclosed by matter; then it's basically saying how much space there is in an object or shape? Also I keep stumbling upon that there are different types of mass like inertial mass or gravitational mass, are they classified by a formula of such?

Reason why I'm asking is because I'm starting to learn physics in a book to get ready for college since I've lost a lot of memory since high school.

Volume does not depend on matter, simply put it is the amount of 3D space in a certain place or object.

For example, if i have an iron ball that is same size as a ping pong ball they will both have the same volume, because the matter inside the space of either ball does not determine the Volume. You could have a piece space with nothing in it but it would still have Volume.

Both mass and volume are linked in the equation:
m=p*V (Mass = Density * Volume)

This basically means that the mass of an object is equal to the density of its material multipled by the space it takes up.
