A 120-sided polyhedron is a hecatonicosahedron.

A polyhedron that has 2 congruent faces is a PRISM. To be a prism, all the other sides (not including the 2 that are congruent) have to be 4-sided.

A 14-sided and 3-dimensional shape is called either a tetrakaidecahedron or tetradecahedron. This 14-sided polyhedron can have six quadrilateral and eight hexagonal faces.

That depends on what the shape of the faces of each side of the polyhedron is - since a ten-sided figure does not create a regular polyhedron, it is impossible to calculate its volume based simply on this information.

no a cuboid is not a polyhedron if it was it would have 9 faces
