I think it was when the nazi was losing and then someone (some soldiers or smth) found the “camp” (later on it was found out that there were more) and by then the nazi had lost and they checked out what had happened
(Sorry if this is wrong, I just finished ss like two weeks ago ;-;)
The correct answer is the sphere. The amount of volume in the sphere is much larger than any other object when compared to the size of the surface area. The surface area of the sphere enables huge amounts of liquid for example to be held in spheres. It is much more efficient when it comes to that ratio than any other structure that is available such as a cone or a pyramid or a cube, or anything similar.
