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.
the answer is a polyhedron!... just saying :)
A dodecahedron is a polyhedron with 12 faces.A dodecahedron is a three-dimensional shape having twelve plane faces.

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.
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.
