THE SIZE OF THE OBJECT DOES NOT MATTER. FOR INSTANCE, A PRISM OF THIS PROPORTION (below) DRAWN AT THIS ANGLE COULD BECOME A BOOK, AN OFFICE BUILDING, OR EVEN A BILLBOARD.
OR, THE EXACT SAME SHAPE COULD BE "LAID DOWN" TO BECOME A "PACKAGE" FOR HORIZONTAL OBJECTS OF SIMILAR PROPORTIONS, e.g., A BED, A CIGAR BOX, A GUN, A BOOK, A SWIMMING POOL, ETC. (Note: Lines #2 which previously converged to the left now converge downwards. Lines #1 which previously converged downwards now converge to right.)
