Even if we change the length by three times or thickness by two-thirds the resistivity will not change as it is the property of the given material
When we change the length and the thickness, the resistivity remains a constant while the resistance changes

Explanation:
The resistance of a wire is inversely proportional to its area and directly proportional to its length. ... 1) When the length is tripled then resistance will also become three times. 2) If the diameter gets tripled then its resistance will become one ninth of the initial reistance.
