Working with Orthographic Projections

Stacking and locking blocks are wonderful manipulatives for working with 3-dimensional objects.  These blocks were purchased from an elementary educational catalog.  The blocks are 1 inch cubes.  In addition to orthogonal investigations, the blocks can be used to investigate surface area and volume of certain solids.
 

Armed with your stacking and locking blocks, can you build the stacks represented by these orthographic projections?
