3d object with 5 faces

The side of a 3D shape is called the face.

In geometry , a deltahedron plural deltahedra is a polyhedron whose faces are all equilateral triangles. There are infinitely many deltahedra, all having an even number of faces by the handshaking lemma. Of these only eight are convex , having 4, 6, 8, 10, 12, 14, 16 and 20 faces. There are eight strictly-convex deltahedra: three are regular polyhedra and Platonic solids , all eight are Johnson solids. In the 6-faced deltahedron, some vertices have degree 3 and some degree 4.

In geometry , a pentahedron pl. There are no face-transitive polyhedra with five sides and there are two distinct topological types. With regular polygon faces, the two topological forms are the square pyramid and triangular prism. The square pyramid can be seen as a triangular prism where one of its side edges joining two squares is collapsed into a point, losing one edge and one vertex, and changing two squares into triangles. Some irregular pentahedra with six vertices may be called wedges. An irregular pentahedron can be a non- convex solid: Consider a non-convex planar quadrilateral such as a dart as the base of the solid, and any point not in the base plane as the apex. It has 2 antipodal point vertices, 5 edges, and 5 digonal faces. This polyhedron -related article is a stub. You can help Wikipedia by expanding it. Contents move to sidebar hide. Article Talk.

Three dimensional shapes can be picked up and held because they have length, width and depth. Faces are the surfaces on the outside of a shape. Edges are the lines where two faces meet. Vertices or corners are where two or more edges meet. The properties of a 3D shape are the number of faces, edges and vertices that it has. The above 3D shape is a cuboid, which is box shaped object. A cuboid has 6 rectangular faces, which are the outside surfaces of a 3D shape. A cuboid has 12 straight edges, which are the lines between the faces. A cuboid has 8 vertices, which are its corners where the edges meet.

In geometry, three-dimensional shapes or 3D shapes are solids that have three dimensions such as length, width and height. Whereas 2d shapes have only two dimensions, i. Examples of three-dimensional objects can be seen in our daily life such as cone-shaped ice cream, cubical box, a ball, etc.
