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.
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.
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.
Circular round face= 1 Flat faces= 1 Edges= 1
It has 2 flat faces, 1 curved face, 2 parallel edges and no 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.
A hexagon is a plane (flat) figure so it has no faces. It has six sides (edges) and six vertices.
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.
