    Mam in this video you have told that for 2D square box, if nx=ny, then degeneracy will be 1. But mam if we consider (5,5) state, this state is degerate with (7,1) or (1,7). Degeneracy becomes 3. Again for 3D box, (3,3,3) state is degerate with (1,1,5), (5,1,1),(1,5,1) state. Degeneracy becomes 4. Mam I think the statement you predicted isn't right.

    If energy is 27 unit than degeneracy is not one(3 3 3)
    But degeneracy is four (1 1 5) ,
    (1 5 1) ,(5 1 1) and (3 3 3)
    So can't apply( x=y=z ) equal to degeneracy one
