re(2): correct me if i'm wrong by Alan)
well Alan......all i gave is the information related to manholes but the basic idea was that there is no variation in its diameter...in case of circular manholes and so their lids cannot fall through.......whatever extra I knew about it was what I posted........but that was not actually the answer to the given question.......as you can see from the subject itself..............
