Calculate Density: Overflow Container w/ $100$ $cm^3$ & $120$ $g$ Stone

[Bobs]

A overflow container that its overflow level is $100$ $cm^3$ has $80$ $cm^3$ water. When a stone that is $120$ $g$ is being dropped into the overflow container, the water increases $10$ $cm^3$.

How to find the density?

I currently don't have any idea about it.

What are the units of density?

What equation relates volume, mass and density?

I just noticed you deleted the template. Please don't do that. It is there for a reason.

That's all are d = m/v but I don't know how to apply it.

In this specific problem, what is m equal to?
