The ability to draw cuboids extremely useful for drawing and painting!
For example look at the next example.. how many cubes and rectangular shapes can you find?
It is not enough to learn how to draw a simple cube, because the cube will appear differently depending on how you view it. It will also appear smaller as it descends from you in to space. (perspective = the view of the viewer!)
It is possible to use perspective drawing techniques to draw cuboids form all angles, which helps with drawing all sorts of things.
