Electron confined in a one dimensional box

  1. May 3, 2016 #1
    1. The problem statement, all variables and given/known data
    An electron confined in a one-dimensional box is observed, at different times, to have energies of 27 eV , 48 eV , and 75 eV .
    What is the length of the box? Hint: Assume that the quantum numbers of these energy levels are less than 10.

    2. Relevant equations

    E=h^2n^2/(8mL^2)
    3. The attempt at a solution
    I tried using that equation to solve for length, but I dont know what energy levels these are at, so i cant seem to solve it.

    energy of the states are proportional to n^2/L^2 and you have energies for three states so can you find out L?
