A 3 dimensional box or cube shape.
Any 2-dimensional shape can be folded to form a 3-d shape. For example, any work of origami.
A pentagonal pyramid has 10 edges.
Rectangles are plane (2-dimensional) polygons. Only solid (3-dimensional) polyhedrons have faces.
A cylinder
a sphere

This question is faulty. Only 2-dimensional shapes can have their sides counted. For a 3-dimensional shape, you must count either edges or faces.
Such a shape cannot exist in ordinary 3 dimensional space.
Is called a Dodecagon. * * * * * A dodecagon is a 2-dimensional (plane) shape with 12 SIDES. The term EDGES is normally used in the context of 3-dimensional objects. One such shape is a parallelopiped. A cube is a special case of a parallelopiped. In 3-D, a parallelopiped is to a cube what, in 2-D, a parallelogram is to a square.
A cube is a 3 dimensional shape with 6 faces, 12 edges and 8 vertices whereas a quadrilateral is a 2 dimensional shape with 4 sides.
The net of a 2 dimensional shape can be folded into a 3 dimensional shape
A 3 dimensional box or cube shape.
There is no simply connected 3-dimensional shape that meets these requirements.
A tetrahedron or triangular pyramid.
Cylinder * * * * * There is no convex 3-dimensional shape with these qualities. A cylinder has two plane faces plus a curved one, and two edges.
There is no 3 dimensional figure with JUST 3 edges.
