An object cannot be 3-dimensional and plane at the same time since the term "plane" refers to 2-dimensional objects, such as geometric figures drawn on a sheet of paper.
However, certain 3-dimensional objects, for instance a cube, are comprised of 2-dimensional (plane) figures (in this case, 6 of them).
On the other hand, a sphere has no plane faces (but theortically approaches an infinite number of them) since no aspect of a sphere can be truly represented on a flat (plane) surface. For practical purposes though, each tiny portion of the sphere could be thought of as a plane figure, and a perfect example of this is a road map.
octahedron
They are simply connected 3 dimensional objects with plane faces.
It is a 3 dimensional figure with 8 plane faces (12 vertices and 18 edges). The top and bottom faces are hexagons and these are joined by six rectangular faces.
A dodecahedron is a polyhedron with 12 faces.A dodecahedron is a three-dimensional shape having twelve plane faces.
the answer is a polyhedron!... just saying :)
Crystal
octahedron
Rectangles are plane (2-dimensional) polygons. Only solid (3-dimensional) polyhedrons have faces.

A three dimensional shape bounded by plane (flat) faces is a polyhedron.
A substance with three-dimensional plane faces is typically referred to as a polyhedron. Polyhedra are solid shapes with flat polygonal faces, straight edges, and vertices. Common examples include cubes, tetrahedrons, and octahedrons, each defined by the number and arrangement of their faces. These geometric forms are fundamental in various fields such as mathematics, architecture, and chemistry.
2 dimensional (plane) figures can have three or more straight edges as sides. 3 dimensional (solid) figures can have four or more plane sides (faces). They can have fewer sides if the sides are not straight.
A 3-dimensional shape. 5 plane faces: 3 rectangular, 2 triangular. Triangular faces parallel to one another. 6 vertices 9 edges
A plane figure is 2-dimensional.
