There are an unlimited number of 3d shapes. Some of these are called polyhedrons, and their names are from the Greek word for the quantity (number) of faces (sides) on each shape. All faces are exactly the same as each other on regularpolyhedrons; one or more faces are different from the other faces on irregular polyhedrons. A few of the countless number of polyhedron names, with the name following the number of faces on the 3d shape are:

4 tetrahedron (a regular tetrahedron is a pyramid with 3 sloping sides and a base)

5 pentahedron (a regular pentahedron is a pyramid with 4 sloping sides and a base)

6 hexahedron (a regular hexahedron is a cube, having 4 sides, a top, and a base)

10 decahedron

12 dodecahedron

24 icositetrahedron

90 enneacontahedron

Some other 3d shapes are:

Sphere

Cube

Cuboid or Rectangular prism

Cone

Cylinder
