I am a bit confused with using the appropriate units. I have two values for density and volume which contain units of:
Density $\rho$ = kg m^-3
Volume v = m^3
One thing i am confused here is why density is per meters negative cubed and volume is per meters positive cubed?
What is the difference between the two ? I am trying to visualize this in my mind in a physical aspect to understand why this is the case but don't fully understand it.
