wire weight = material_density * 3.14159 * (0.5 * cable_diameter)² * cable_length
example for copper with 152 meter length:
----------------------------------------
material_density for copper = 8960 kg/m³
cable_diameter=0.006 meter
cable_length=152 meter
weight of wire = 8960 kg/m³ * 3.14159 * (0.5 * 0.006)² * 152 = 38.51 kg
lenght and diameter must be calculated in "meters"
density must be in "kg/m³"
It depends on the length of th cable and the diameter of the copper cable used.

I believe intrinsic impedance is more tied to the medium, thus is defined in terms of magnetic and electric permeability and electrical conductivity, while characteristic impedance is a "wider" look at the impedance. For example, you can calculate the intrinsic impedance of a 18 awg copper wire, or air, or a vacuum. If you wanted to use coax cable with an 18 awg core, you would be looking at the characteristic impedance, not the intrinsic impedance of the copper that will be carrying the waveform.

Copper and aluminium are used for electric cables.

Basic calculation is: no. of cores x cross-section of one core x 9,6 = copper weight in kg/km e.g. copper weight for cable 4x2,5 = 4 x 2,5 x 9,6 = 96 kg/km This is how cable manufacturers calculate the copper weight. Pls notice that it's valid formula only for cables without screening/shielding. If you know cross-section of screening, you can add that to the formula.
depends how thick it is
Copper is much cheaper but still does the same job almost as well as silver.
Metals and particularly copper, are good conductors of electricity a prerequisite for an electric cable. In addition, they are ductile enabling them to be drawn out easily into wire/cable.

Copper is a better conductor by weight, but aluminum is better by weight, so the copper will be thinner but heavier. You will see that a 250 kcmil aluminium wire will get you 170 amps at 60 degC while a 000 (or 3/0) copper wire will get you 165 amps at 60 degC. I think you mean circular mils, not square millimeters.

copper cost more to mine then aluminum so aluminum will cost less then copper cable.
A copper cable transports electrical signals. An optical cable transports light signals.
