From the formula: density=mass/volume

But first, we have to convert the cm³ to m³ by multiplying the value in cm³ by 10^-6, by so doing we'll have the volume to be 0.48*10^-3cm³.

we will also need to convert the mass which is in g to kg by simply dividing by 1000 so the mass becomes 0.12kg

Now we can solve for the density using the formula I earlier stated which is the mass divided by the volume = 0.12/0.48*10^-3 so the density will be 0.25*10^3kgm-3 or 2.5*10^2kgm-3
