A step prism has a stepped rectangular cross-section extruded through a constant depth. Split the front face into two rectangles: the lower one is L × H1 and the upper one is W × (H2 − H1). Add those areas, then multiply by the depth D. Volume = ((L × H1) + (W × (H2 − H1))) × D. Answers are in cm³. Diagrams are not drawn to scale.
