CROSS SECTIONS OF A RIGHT RECTANGULAR PRISM A prism is a three-dimensional figure with opposite sides that are parallel and of the same shape and size. Rectangular prisms have rectangular bases and rectangular faces that are perpendicular to the bases. A rectangular prism has all sides of the same length. A cross section parallel to the rectangular base is congruent to the rectangular base. A cross section along the diagonals of opposite faces is also rectangular and congruent to a pair of faces. What is the shape of each cross section?
