A piece of metal with a density of 4.69g/cm^3 and a mass of 1500 grams, is submerged in a container of oil, with a density of .75 g/cm^3. What volume of oil does the metal displace?
I'm not sure what equations to use? I know p=m/v and B=pvg.

The volume of the fluid displaced equals the volume of the piece of metal. That volume is mass/density = ??
Check my thinking.

which density do I use?

Use the metal's density, because you want the volume that the metal occupies or "displaces". You don't need the density of oil to answer the question.
