The answer depends on the orientation of the plane that cuts the cube.
If the plane is parallel to a face of the cube then you will have two square based prisms.
If the plane inclined to two of the cubes faces but perpendicular to the third it will be two parallelepipeds.
If the plane passes through one pair of adjacent vertices as well as the opposite pair, it will be two triangular (right angled-isosceles) prisms.
It could also be two hexahedra with two pairs of parallel but non-congruent faces.

You ether cut it in half or fourths or eighths(do you get the idea?)
when you cut a pentagon in half you create a trapizoid
