A face is the flat surface on a solid figure. For example, a triangular prism has five flat surfaces and therefore five faces.
The solid figure that has 2 flat surfaces and 0 vertices is a cylinder. A cylinder consists of two parallel circular bases (the flat surfaces) connected by a curved surface. The bases do not have any vertices, as they are continuous curves.
The flat surface of a solid figure is called a face. For example, a rectangular prism has 6 flat surfaces and therefore 6 faces.
