If an object has a density of 10g/cm^3 and is cut into two equal parts, what is the density of each piece? Why?

The density of each piece remains at 10*g*cm^-3.

Explanation:

"Density" is an "intensive property", a property that depends on the nature of the material, unlike the "extensive properties" such as mass and volume, which are determined by the extent of the material.

We have rho=10*g*cm^-3; if we halve the volume, reasonably we halve the mass, and rho remains constant.
