WebAnswer (1 of 2): It isn't, in general. The solid angle subtended by a closed surface is 4 \pi for interior points. The appropriate generalisation here is not to include lots of weird and wonderful surfaces. It's really simple; “completely surrounded in all directions in three dimensions” means “... WebDraw three sides of a square (the bottom line and the two side lines) Then put a peaked roof on it like the roof of a house. There you have five lines which is the definition of a pentagon (when you see the prefix PENT, that means 5) In this case, you will also see the two right angles where the bottom line and the two vertical lines meet.
