A solid metal cylinder is placed on a horizontal surface, as illustrated. The cylinder has length $x$ and cross-sectional area $A$. The cylinder produces a pressure $p$ on the surface. The acceleration of free fall is $g$. Which expression gives the density of the metal in the cylinder?
- A$\frac{gx}{p}$
- B$\frac{p}{gx}$
- C$\frac{gx}{pA}$
- D$\frac{pA}{gx}$
