If you're asking "How many surfaces are there on a 3-dimensional cone? then the answer is 2: The first surface is the circular base. The 2nd is the actual "cone" part that wraps around to a point above the circle.
#1 a cone is 3d and a rectangle is 2d. #2 a cone has a circular base and a ractangle has 4 sides that only 2 are parralel

no stupid because one has got faces(3d) and the other has sides(2d)

It is impossible to count the edges of a 3d anything. A cone is 3D anyway so it is impossible. Another reason it is impossible to count the edges is that a cone is made out of circles. If you drew a 2D cone, it wouldn't be a cone anymore, it would be a triangle. So, in essence, a cone is a tri-agnle which has three sides; but a cone is 3D and, as I said before, the edges cannot be counted on a 3D object.
A cone only has a base, no sides
2 sides, the base and the cone.
The cone IS a 3d figure.

A cone has no acute angles because a cone is a 3D shape and not a 2D.

The base of a cone is a circle, and circle have an infinite amount of sides
