Mathematically, a cone is infinite and so has no flat surface. The popular cone is actually a truncated cone and does have 1 flat surface.
Its base is a flat surface
a cone has one flat surface one vertex and no edge.
A cone has 1 flat surface, because a cone has 1 corner and has 4 edges. The reason that is is because a cone is round. A cone has a flat surface at the bottom of the cone. The reason it is because the cone doesn't have any vertices and most of the solid and plane figures have vertices.
its a cone cones dont have a flat bottem
A cone !!
An empty cone (like an ice-cream cone) doesn't have any flat surfaces. It has two curved surfaces, one outside and one inside. A solid cone has a flat base, and one other curved surface.
It only has one. the face going around the cone is called the lateral surface
