Yes, it does.
A cuboid. Or a hexagonal prism. In fact any prism whose base has an even number of sides will have three pairs of opposite parallel congruent faces. All but the cuboid will also have other faces but the question does not exclude them.
Each face of a cuboid is just as special as any of the other faces.
Yes. A square consists of two pairs of parallel lines!
A polyhedron is any multi-faced solid. In order to know how many pairs, you need to know how many total faces.
A heptahedron is a seven-faced polyhedron. The number of pairs of parallel faces in a heptahedron can vary depending on its specific shape and configuration. For example, a regular heptahedron, such as a truncated triangular prism, may have pairs of parallel faces, while other irregular heptahedra may not have any. Therefore, the answer is not fixed and can range from zero to multiple pairs based on the specific heptahedron in question.
There cannot be any such object as a cylinder cuboid.
its has parallel faces and edges
Prisms with any number of sides can have perpendicular faces. Often both end faces are perpendicular to the length. In the case of a REGULAR octagonal prism, there will be four pairs of parallel faces, where each face of a pair will be perpendicular to the two faces of one of the other pairs. There is not much that can be said with certainty about an irregular octagonal prism.
No. It has four rectangular and two squares, or six rectangular faces.
A pyramid never has parallel faces. Any two faces intersect.
The two circles at the top and bottom of the cylinder are parallel faces.
Cube, Cuboid. Any prism with a quadrilateral cross section
