A 3D star is not a standard shape. You can easily add another point.
A 3d rectangle, or a cuboid, has eight corners.
No corners and two edges !
If it is a polyhedron, then four or more faces and four or more corners.
It has 5 corners if it is a 3D shape like a piramid but if it is 2D it is 3
It has 6 faces, 12 edges and 8 corners or vertices
A 3d rectangle, or a cuboid, has eight corners.

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.
If it is a polyhedron, then four or more faces and four or more corners.
5*2=10 corners in total
To make a 3D star origami, start with a square piece of paper. Fold it in half diagonally both ways, then fold the corners to the center. Fold the edges to the center line, then fold the flaps outwards. Finally, shape the points to create the 3D star.

About 26 sides, and 24 corners.
Cuboid has : 8 corners (vertices) 12 edges 6 faces
There are 4 corners in a flat rectangle and 8 corners in a 3d rectangle(rectangular prism).Four.
