That's a Sphere not Cylinder cuz it had flat Circles Above and
A polyhedron
The face of a triangle is the flat surface of the solid figure. _________________________________________________ A face is a side of a 3 dimensional figure. So, the number of faces a triangle would be 0.
Twelve regular pentagons comprise the faces of a dodecahedron.

A cube is a solid figure called a polyhedron. A polyhedron is a solid figure with all flat faces. So a cone would be a solid figure but not a polyhedron becasue it has a curve and does not have all flat faces.
The flat surface of a solid figure is called a face. For example, a rectangular prism has 6 flat surfaces and therefore 6 faces.
A face is the flat surface on a solid figure. For example, a triangular prism has five flat surfaces and therefore five faces.
A square is not a solid figure at all. It's a flat figure, with four congruent faces and four congruent angles.

A pyramid has 4 flat faces, all of which are triangular. Don't confuse this with a square-based pyramid like those in Egypt, as they have 5 faces.
