A metal ball is fastened to a cork and lowered into a measuring cylinder, which draws the cork down into the water, as shown. The mass of the cork is $4.8\,\text{g}$. Find the density of the cork.
- A$0.15\,\text{g cm}^{-3}$
- B$0.20\,\text{g cm}^{-3}$
- C$0.60\,\text{g cm}^{-3}$
- D$5.0\,\text{g cm}^{-3}$
