A pentagonal pyramid.
the 3d shape that that has no flat face is the circle
A 3D triangle, commonly referred to as a tetrahedron, has four flat surfaces. Each surface is a triangle, and the tetrahedron is the simplest form of a polyhedron. It consists of four vertices and six edges as well.

Sphere
it is a 3d shape because it is not flat
a cube
on a 3D object to find the surface is to look on all flat surfaces. yourwelcome
A common 3D shape that is not a polyhedron is a sphere. Unlike polyhedra, which are formed by flat polygonal faces, a sphere is characterized by its smooth, curved surface and has no edges or vertices. Other examples of non-polyhedral 3D shapes include cylinders and cones, which also feature curved surfaces.
