Ohm's Law has nothing whatsoever to do with the factors that determine the resistance of a conductor.

The resistance of a conductor is directly-proportional to the resistivity of the conducting material and to its length, and inversely-proportional to its cross-sectional area.

Ohm's law states that at a constant temperature, the current flowing through the conductor is directly proportional to the potential difference across its ends.

As Ohm's Law actually applies to so few materials, it doesn't warrant an explanation, and there is a good argument for scrapping Ohm's Law altogether.
