WebSome examples of the 3D shapes are a cube, cuboid, cone, cylinder, sphere, prism and so on. Types of 3D Shapes. The 3D shapes consist of both curved shaped solid and the straight-sided polygon called the polyhedron. The polyhedrons are also called the polyhedra, which are based on the 2D shapes with straight sides. WebMar 28, 2024 · Face – The flat surface of a polyhedron.; Edge – The region where 2 faces meet.; Vertex (Plural – vertices).-The point of intersection of 2 or more edges. It is also known as the corner of a polyhedron. Polyhedrons are named based on the number of faces they have, such as Tetrahedron (4 faces), Pentahedron (5 faces), and Hexahedron (6 faces).
