An edge is where 2 faces meet, again some can be straight, some can be curved e.g. a cube has 12 straight edges whereas a cylinder has 2 curved edges. A corner is where 3 edges meet. A cube has 8 corners, as does a cuboid. A sphere has no edges and therefore no corners.
Hereof, how many faces are on a sphere?
All of these figures are curved in some way, so they have no edges or vertices. What about their faces? A sphere has no faces, a cone has one circular face, and a cylinder has two circular faces. Therefore, the number of faces increases by one from one figure to the next.
How many faces are in a cone?
A cone has one face. It is a three-dimensional shape with a circular base, one side and one vertex. Faces can be identified as the flat surfaces on a three-dimensional figure.
How many faces has a cylinder?
