The question I am struggling is number 12 (c)(ii) which starts on page 14, but my part is on 16, the very last question of the paper
http://www.hinchingbrookeschool.net/science/documents/2864June2003.pdf
I want to calculate the length of a box where n = 3
[tex]E_{n} = n^{2}E_{1}[/tex]
Therefore for the n = 3 quantum state, E = 1.215x10^-21
But the markscheme goes into somthing completely different, so I must be taking the wrong route. If I work it through I get the wrong answer
Page 32 ON Mark Scheme:

Can someone explain my misunderstanding of the physics involved here?
Thanks :)
