A 51.0 g sample of a conducting material is all that is available. The resistivity of the material is measured to be 12 108 ยท m, and the density is 7.67 g/cm3. The material is to be shaped into a solid cylindrical wire that has a total resistance of 1.5 .
What length of wire is required?
What must be the diameter of the wire?

Is the 12*10^8 resistivity in units of ohmcm and the wire resistance in ohms? You have omitted some symbols.

The 12*10^8 is in ohmm, and the wire resistance is in ohms. I copy pasted the question from "WebAssign" so I guess the symbol for ohms did not transfer over.
