A dodecahedron is a polyhedron with 12 faces.A dodecahedron is a three-dimensional shape having twelve plane faces.
I suggest a 3-dimensional star shape, each of whose faces are not plane but concave.
There are many plane shapes comprising 4 squares and 2 rectangles but there is no such 3-dimensional shape.

No, a square is a two dimensional plane figure.

A 3 dimensional figure
the 3 dimensional shape is a octagon, because their are 8 sides.
A pyramid
a nonahedron.
A 3-dimensional shape. 5 plane faces: 3 rectangular, 2 triangular. Triangular faces parallel to one another. 6 vertices 9 edges

Cylinder * * * * * There is no convex 3-dimensional shape with these qualities. A cylinder has two plane faces plus a curved one, and two edges.
If its 2-dimensional then its an octagon, if it is 3-dimensional then it is called an octahedron.
