What is the name of a 3D polygon?
polyhedron
A three-dimensional shape whose faces are polygons is known as a polyhedron. This term comes from the Greek words poly, which means “many,” and hedron, which means “face.” So, quite literally, a polyhedron is a three-dimensional object with many faces. The faces of a cube are squares.

How do you identify 3D shapes?
Faces, edges and vertices are three important measures of 3D shapes, that defines their properties.
- Faces – A face is a curve or flat surface on the 3D shapes.
- Edges – An edge is a line segment between the faces.
- Vertices – A vertex is a point where the two edges meet.

Sphere. Torus. Shaped like a ball or a globe a sphere is a completely round object. Every point on the surface of a sphere is an equal distance to the centre of the sphere.
What is a 3D rhombus called?
In geometry, a rhombohedron (also called a rhombic hexahedron or, inaccurately, a rhomboid) is a three-dimensional figure with six faces which are rhombi. It is a special case of a parallelepiped where all edges are the same length.

A hexagonal prism is defined as a prism with a hexagonal base and top. A hexagonal prism has 8 faces, 18 edges, and 12 vertices. Out of the 8 faces, 6 are parallelograms, and 2 are hexagons, and that’s why it is called a hexagonal prism.
