How to Shade Cubes : Adding Shadows to Cubes
We will show you each step to be taken in shading a cube in this tutorial, for this solid is a representative of all prisms, and, indirectly, of the cylinder.

The top face will be the brightest of those seen, and the darkest will necessarily be that next the cast-shadow.
