This is a very simple question,

Which one has more surface area a 50ml conical flask or a 50ml beaker.

Thanks.

If its so simple, why don't you write some surface area equations for us.

For cylinder

A = 2?rh + 2?r2

The first term calculates the area of the sides and the second term the area of the top and bottom.

Well a beaker doesn't have a top so what will you have to do to the equation to account for that?

Are there any other conditions?
If the breaker is very slender?There must be other preconditions!
