Yes the formula of resistivity is:

$R=(\rho l)/(A)$

Where
$\rho$ is relativistic resistance with units
$(\Omega)/(m)$ , each metal has different relativistic resistance you must find the relativistic resistance of your material using the table of relativistic resistances.

stands for the length of a wire.

stands for the area of the wire. Usually it is equal to
$\pi r^2$ because.

So now we have data
A=1cm^2 but nothing else was specified so we are unable to calculate anything.

Hope this helps.
