A 3D shape with 11 sides is known as a hendecagon or undecagon when referring to its 2D counterpart, but in three dimensions, it can be represented as a polyhedron with 11 faces. One example could be a prism with an 11-sided polygon as its base, resulting in 13 faces (11 rectangular side faces plus the two bases). The specific properties of such a polyhedron would depend on the arrangement and shape of the faces.
A 3d shape can have infinite sides
hello you should get a life
sides are the face of a 3d shape and verticies are the corner of the shape
A septadecahedron has 17 sides to it.
