What if pupils find this a barrier?
Give examples in different orientations to help pupils focus on identifying the faces that represent the uniform cross-section. If necessary go back to using interlocking cubes, but establish the general formula.
Give pupils opportunities to explore generating prisms from fixed volumes.
