Any kind of prism...:)
Shapes have sides. Do you mean, what shape has 6 sides or, what solid has 6 faces?
Since a cube has 6 faces, you would be looking for a solid shape with only 2 faces and no such solid exists.
Shape
A solid shape with 6 faces, yes. A plane shape with 6 sides is a hexagon.
triangular pyramid
There is no regular solid with 13 faces.
tetrahedron
Depends. What shape is it?
a sphere
A polyhedron (solid shape formed by plane faces) with four faces is called a tetrahedron.
A cube has 6 faces
A cube is a 3D shape that has 6 faces of equal area.
