There must be more information. Is there a table of reference where you can look up resistivities and such?

There's this formula for resistance but you also need alpha (temperature coefficient of resistance) for the metal:
R = Ro [ 1 + alpha (T - To)]

Ro = Resistance of Tungsten at 20 C
Given same dimensions, R of Tungsten = 5*R of Copper at 20 C
To = 20 C
alpha = temperature coefficient of resistance of Tungsten
T =?

This is my initial thought though, given you have these values which should be in the back of most physics textbooks. I might have missed something crucial here though, I'm not sure.
