it is the property of solid crystal that they have straight edges and flat faces.
A polyhedron is in a subclass of geometric solids. The difference is that a polyhedron must have flat faces and straight edges.

it is the property of solid crystal that they have straight edges and flat faces.
Polyhedron is a geometric solid in three dimensions with flat faces and straight edges.
Polyhedra are three-dimensional shapes with flat faces, straight edges, and sharp corners. They have vertices (corner points), edges (line segments where faces meet), and faces (flat surfaces that make up the shape). The properties of a polyhedron include its number of faces, edges, and vertices, as well as the types of faces that make up the solid.
A polyhedron is in a subclass of geometric solids. The difference is that a polyhedron must have flat faces and straight edges.
A polyhedron is defined as a "geometric solid in three dimensions with flat edges and straight faces". As both cylinders and cones have curved faces, neither are polyhedra.

No, a pyramid is a polyhedron with flat faces and straight edges.

This shape is a cube.
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.
