write the dimensions of specific resistence?

We know that the wire length is 2300 feet for each piece of wire, but how do we determine the amount of resistance for a specific size and length of wire? To do that, we need another formula: R=( rho)L/A This formula relates the resistance of a conductor with its specificresistance(the Greek letter "rho" (?). L is lenght of wire and also A is cross sectional area. so specific resistance rho = RA/L.
