In geometry, the hexagonal prism is a prism with hexagonal base. This polyhedron has 8 faces, 18 edges, and 12 vertices. Since it has eight faces, it is an octahedron. However, the term octahedron is primarily used to refer to the regular octahedron, which has eight triangular faces.
Rectangular Prism. A polyhedron with two congruent and parallel faces and whose lateral faces are parallelograms. Prism are often distinguished by the shape of their base polygon. A prism with rectangular bases is a rectangular prism. Rectangular prism is a 3-dimensional solid object which has six faces that are rectangles. A rectangular prism has two ends and four sides. Opposite sides of the rectangular prism have the same area. A vertex is the point on 3-D shape where two or more edges meet. More than one vertex contained by a object is called vertices.
