A cube is a 3D shape with a top and bottom.
A 13-faced 3D shape is known as a triskaidecahedron. Specifically, if it has 13 faces that are all pentagons, it is referred to as a regular triskaidecahedron. In general, any polyhedron with 13 faces can be classified under this name, but the specific type can vary based on the shape and arrangement of the faces.
It is important to learn and remember the name of 3D shapes. A 19 faced 3d shape is called a nonadecahedron.
The simplest such shape is PYRAMID.
A tetrahedron.
A hexahedron is the name for a 6 sided 3D shape.
A nonagon is a 2D shape and there is not a 3D equivalent shape.
the name of a 20 sided 3d shape is called a icosahedron
