No corners and two edges !
a cylinder has no corners
A 3d rectangle, or a cuboid, has eight corners.
A cylinder has three sides and no corners.
No corners and no edges.
there are no corners and there are 3 faces
none
There are 4 corners in a flat rectangle and 8 corners in a 3d rectangle(rectangular prism).Four.
I just want to say that no 3D shape has corners, they have vertices (singular vertex), which is what you might call a corner, but this is the correct terminology.A sphere has no corners (as it is 3D), but it also has no vertices.
A 3D star is not a standard shape. You can easily add another point.
None of them has any.
