Using density to find volume If you know the density of a substance and the mass of a sample, you can find the volume of the sample. This time, you will rearrange the density equation to find volume.
text(volume)=(text(mass))/(text(Density))
Sample problem: The density of lead is 11.3 g/cm3. Find the volume of a 525 gram block of lead. To solve this problem, divide the mass of the block by the density of lead.
text(volume)=(525 text( g))/(11.3 text( ) (text(g))/(text(cm)^3))
The volume of the block is 46.5 cm3.

Try these problems on your own.
