Density can be calculated by:
[tex]D=\frac{M}{V}[/tex]
where D is the density, M is the mass, and V is the volume. In this case we have m = 360g, V=7.5 cm^3 by plugging in these values we have:
[tex]D=\frac{360g}{7.5cm^3} =48\frac{g}{cm^3}[/tex]
C.) 480 g/cm^3
Pro-tip: Look at the units, they sometimes tell you what to do. In this case all of your answers have grams over cm^3 this means grams divided by cm^3. Even if you do not know the equation you can infer what it is by knowing what units you have vs. what units you should end up with.
