Okay, honestly after solving the question I haven't found THE ANSWER I am trying to find.
The question is
 "Find the surface area and volume created by revolving  ln (x)x >=1
  around the x-axis, Surface area in mm is your score"
But the catch is, that there is supposed to be a real number hidden in the solution ( I am not sure) which is what I am trying to find.
The real no. Might be around 400-600 of range. Pls help! (This came up after I asked my marks in a particular test, the teacher told me to find the marks by solving this and that's the no. I am trying to find).
