if the man cover is not having the shape of a circle, then there is a chance that the hole won't be covered properly every time... but if it is having the shape of a circle.. then no matter how you place it it will close the hole perfectly..

You guys are on the right track, but let's put it this way. Lets say it was a square. The sides are each "x" length, so the diagonal of the square is x * sqrt 2. Therefore, positioned correctly, the cover would be able to fall in, since there is a way for the opening to be greater than the length of one of the sides. With a circle, it's always diameter D and it can't fall in.

disc shaped manhole cover doesn't have to be rotated to fit into the manhole opening (thanks Wikipedia!)

So, the cover doesn't fall in, that's the correct answer

Man holes covers are heavy... so if they are circular, we can roll them.
Also, for a man to enter a man hole, the smallest area needed is a circle.
Also, the cover wont fall into the hole if it is circular. if it was square, there is a chance of falling.

"Also, the cover wont fall into the hole if it is circular. if it was square, there is a chance of falling."

I do not understand the logic behind this statement. How does the shape matter if the manhole is built such that it holds the cover appropriately? Are you bringing in some theory of gravity and surface area?

Have you ever heard of the Pythagorean Theorem?

The only and main reason of why manholes are round is because is the simpliest way to prevent falling into the manhole.

I can't believe you are still asked these kind of questions at an interview.
