I believe the question on resistivity is wrong. the resistivity of an object formulated p=RA/L. p being a conductors resistivity, R it’s resistance, A the cross sectional area, and L bring the length. One example of this is looking at voltage drop for long power cables. The longer the cable/conductor the more resistivity it has and the greater the voltage drops over the conductor.
That question tripped me up, but I am now wondering if the question asked about a conductors resistance and not its resistivity. Resistance, being a material property, is dependent on temperature and not geometry.
