it is the property of solid crystal that they have straight edges and flat faces.
The three parts are faces, vertices and edges. The faces are the flat surfaces, the edges are the lines that joint the corners which are called vertices.
flat surfaces: 6 faces: 6 edges: 12 corners: 8
cylinder has 3 faces,1curved faces,2 flat faces and 2 curved edges

If they are flat, they are faces. If they are pointed, they are vertices and if they are thin and long they are edges.
A sphere has no edges, because an edge is defined as where two faces meet. Likewise, it has no faces, because a face is defined as the flat surface of an object. Likewise, it has no corners either.
A face, of a solid object, is a flat surface. If it is curved it is called a curved surface though sometimes it is also referred to as a face. Two faces meet at an edge, which is a line which may be straight or curved. Three or more faces meet at a point which is a vertex.
A rectangular prism is solid 3-dimensional object which has six faces that are rectangles. It has 12 edges and 8 vertices.
The flat surface of any three dimensional object is called a face; a prism is a three dimensional object.A tetrahedron has 4 faces, a cube has 6 faces, an octahedron has 8 faces, etc.
Circular round face= 1 Flat faces= 1 Edges= 1
Sphere
A face of a polyhedron is one of the flat surfaces. These are two dimensional objects. Two faces meet at an edge, which is a line - a one dimensional object. Three or more edges meet at a vertex which is a point. A point has no dimensions.
