Finding length and diameter of wire

[dev-hud]

Suppose you wish to fabricate a uniform wire out of 1.0 g of copper (Density of copper is 8.93 x 10^3 kg/m^3). If the wire is to have a resistance of R = .5 ohms, and all the copper is to be used, what will

a) the length and
b) the diameter of this wire?




R = .5
a weight of 1.0 grams. how am i suppoise to find length and diameter (im assuming cross sectional) of the wire with only given these 3 variables??

You'll probably also need to look up the resistivity of copper
