Question

Good evening 

I posted this question and got like a photo from a solution book . Not taking anything away but certain terms are not even being used in this stage of Radiation   physics like the Hamiltonian operator. (Classical mechanics) please see solution given . I need just someone to please explain the solutions ( symbols being used etc) and the steps

Calculate a three-dimensional infinite square well potential of dimensions a,b and c in the
x,y and z dimensions, respectively.
(a) Write time-independent 3D Schröedinger equation in Cartesian coordinates and the
corresponding general solution.
(b) How many and which are the quantum numbers (nx, ny, nz) degenerate states will exist
for the fourth energy state (E4)?
