A cube has six plane surfaces -- top, bottom, and four sides.

A cube has three planes of symmetry.
According to Websters: Prism: a polyhedron with two polygonal faces lying in parallel planes and with the other faces parallelograms. That would describe a cube. so Yes.
It depends on which type of cuboid we are talking about. If it is a CUBE (a special type of cuboid), then it has nine planes of symmetry. If it is a cuboid with length, width and height all different, then it has three planes of symmetry. If it is a cuboid with two equal measurements (say width and length), then it has five planes of symmetry.
A cube has 8 vercities.

There are 56 such planes.

There are 12 edges on a cube. There are 5 flat surfaces (planes) on a cube as well.
A rectangular solid that is not a cube has 3 planes of symmetry.
No, but they are part of planes.

A cube has three planes of symmetry.
27 cells. It is a 3-dimensional 3-sided cube (3 planes of 3 squares) which is 3x3x3 = 27.
Individual points on one side of the cube are coplanar. Points on one side might not nessasarily be coplanar with points on another side. The corners of a cube are exactly coplanar to three planes, but not all planes of the cube. In fact, no point on the cube is coplanar to all other points on the cube.
