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.
A 3D cone has two distinct surfaces: one curved surface that wraps around the cone and one flat circular base. Therefore, it can be said to have one curved side and one flat side, totaling two sides. However, in terms of edges and vertices, a cone has one edge (the circumference of the base) and one vertex (the tip of the cone).
#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)
A cone has one curved surface and a circular base, which can be considered as one flat side. Therefore, in a 3D context, it can be said to have one side (the curved surface) and one base, but typically it is referred to as having one continuous surface. Overall, a cone is often considered to have one primary side.
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
