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
The solid shape with 6 rectangular faces where not all sides are identical is called a rectangular prism, also known as a cuboid. It has opposite faces that are equal in size, but the lengths of the edges can vary, resulting in different dimensions for each face. This shape is commonly found in everyday objects, such as boxes and bricks.
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
