There is no greatest. Any polygon you draw, no matter how many sides it has,
I can always draw a polygon with more sides than yours has.
They don't all have names, but there's no limit to the number of sides they can have.
A polyhedron is a solid whose faces are polyhedra, so the question is rather meaningless.
The simplest shape is a hexagonal prism.
A prism.
It is a prism.
The greatest number of sides can be any amount of sides.
A polyhedron is a solid whose faces are polyhedra, so the question is rather meaningless.
Prism
A prism *always* has 2 bases. In case you meant "faces" instead of "bases", the prism with the smallest number of faces is the triangular prism - which has 5 faces. If there were any fewer number of faces, the prism which become a two dimensional object.
These are terms which are used in the context of polyhedra. A polyhedron is a 3-dimensional, solid shape which is bounded by polygons. Every such polygon is a face. However, some faces are also called bases and this depends on the polyhedron.All the faces of a pyramid, with the possible exception of one, are triangles. The one different face is called the base. In a triangular pyramid (tetrahedron) the face that is at the bottom is the base.A prism has two identical, parallel faces which may be any polygon. All the other faces are rectangles. A non-rectangular faces are called the bases. In a cuboid all six faces are rectangles and so any pair of opposite faces are called bases.
A solid figure with two congruent polygonal bases connected by lateral faces that are rectangles is called a prism. The two bases can be any type of polygon, such as triangles, squares, or hexagons, and the lateral faces are perpendicular to the bases. The height of the prism is the perpendicular distance between the two bases. Examples include triangular prisms and rectangular prisms.
A polygon. A prism has two identical bases or end-faces and these can be polygons with any number of sides.
A shape is classified as a prism if it has two parallel, congruent bases connected by rectangular lateral faces. The bases can be any polygon, and the lateral faces are perpendicular to the bases. Additionally, the cross-section of the prism remains consistent along its length. If these criteria are met, the shape is a prism.
