+**a)** Assuming the Sommerfeld model, and starting from a sketch of allowed traveling wave states in k-space, show that //n//_3d = (//k//_F)³/3π².
 **b)** Do the same thing for a one-dimensional electron gas, i.e. relate //n//_1d to //k//_F (now the electron traveling waves are described by only //k//_x).
 **c)** Estimate //n_3d// and //E//_F for gold using physical/chemical parameters such as density and electron configuration.
