A cube or a cuboid
the shape that has parallel face is circle
It is a cube.
A regular dodecahedron, for example. Each face is a regular pentagon so no face has parallel sides. However, the edges on opposite faces are parallel to one another.
Because the horizontal surface is curved it is not called a face.
Only the base can have parallel edges since all other faces are triangular. So, at most one face.
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.
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.
A shape face is basically a face on a shape eg: there are 6 faces on a cube and cuboid so there is your answer!
For a uniform hexagonal prism, there are four pairs of parallel sides. On a hexagonal prism, the six side faces have interior angles of 120 degrees, so each face is parallel with one three over from it. The ends (base and top) are parallel and 90 degrees from each side.
..... 2 opposite parallel flat faces
There cannot be such a shape. It is not a cylinder because a cylinder sdoes not have a rectangular face. A rectangle must be a flat face and the only flat faces in a cylinder are the circle faces. The curved face can be "opened out" into a rectangular shape but because the face is curved it cannot be rectangular.
the sides of a shape! ex: a cube has 6 faces!
