So, faces? Well, just the one. Edges? Zero. Vertices? None. Oh dear! Oh well. The spheres are disappointed and one is angry. 3D shapes have faces (sides), edges and vertices (corners). Faces - A ...

For example, this cuboid above 6 faces, 12 edges and 8 vertices. The table below shows how the faces of some other 3D shapes compare. A Carroll diagram is a table that can be used to group shapes ...

Flattening of the 3D shape on the surface in this preferred way involves only angle changes at the vertices and minimal stretching or compression of any edges, which is expected as the angle ...
