Why are manholes round?

SherlockHolmes Expert Asked on 5th November 2018 in

1)   Circular covers don’t need to be rotated or aligned when placing them on the opening . but if you take an example of triangular covers you have got to slightly align in a                particular way to fit in the opening.
2)   Circular covers never fall inside their opening..but where as if taken an example of square covers , it could fall inside if it is inserted diagonally.
