1. The problem statement, all variables and given/known data
On page 249 of ISSP, Kittel says that the radius of a free electron Fermi sphere is

[tex]k_F = \left(3 \pi^2 n \right)^{1/3}[/tex]

where n is the concentration of electrons.

I don't know why that is true.

EDIT: never mind; they derive that on page 138


2. Relevant equations



3. The attempt at a solution
