If a building the shape of pyramids slops downwards, wouldn't it minimize the risk of fall from heights, whether intentionally or by accident (like fire/bomb scare), from a balcony or window opening? That is discounting falling in a lift shaft or stairwell? Perhaps Egyptians were smart in that sense?

  • $\begingroup$ I guess angle depends on height of the building? $\endgroup$

1 Answer 1


If you take the ancient Egyptian pyramids as an example, the slope angle of the sides is greater than 50 degrees. You can also experiment with pyramid dimensions and walls angles using this website.

People may not "fall" to their deaths from such pyramids, but they will slide to their deaths.

To prevent anyone from sliding to their death from a pyramid the wall angles would need to be less than the angle of sliding, which for most situations would be less than 30 degrees.

  • $\begingroup$ @DKNguyen: If the the pyramid was tall enough, most likely. $\endgroup$

  • $\begingroup$ Oh then why don't people who ride water slides at theme park slide to their death? $\endgroup$

  • $\begingroup$ @Nederealm: water acts as a transporting medium. Before they can hit the bottom of a water slide, the water moves them along to a safer & shallower part of the slide. Without water, people would hit the bottom. $\endgroup$
