What is 3.00g/cm^3?
You have a slice of pizza. You take a few bites of the slice of pizza. Did the density of the pizza change?
No! The mass changed because you ate it, and the volume changed because you ate it, but that keeps the density the same.

What is 1.5 g/cm^3?
How does a decrease in volume of an object affect the density of the object?
Density is how tightly packed atoms in a substance are. If you make the substance smaller, but don't change the amount of atoms, the atoms will be tightly packed.
