I'm working on a problem concerning energy levels in a 3D box.(adsbygoogle = window.adsbygoogle || []).push({});

I have calculated the energy levels in eV using the standard equation:

En = { { ∏^2 (h-bar)^2 } / 2ma^2 } (n^2 + n^2 + n^2)

Are these calculated energy levels the total energy per level?

Or does the energy E calculated using this formula apply to each state within that level?

Thank you.
