    I’ve heard the following answers:

    1.Manholes are round to prevent them from falling in. (covered in your comments)

    2.Manholes are round to make them easier to handle, i.e. roll (covered in your comments)

    3.Manholes are round because the round shape distributes the weight of vehicles driving over them most efficiently thereby allowing them to be lighter
