Pyramid Confusion

[βαθμιαίος]

Re-reading my previous post, I don't think I made it clear that IMO the apex angle only matters for open pyramids. For a small solid pyramid to be used for putting beneath a pillow or chair Ra said that the great pyramid at Giza was an excellent model, and that pyramid has a 76° and 18' angle at the apex.

In the process of looking that up I also ran across the divinecosmos thread on pyramids, which has some good information as well as a link to a guy who builds and sells wooden pyramids, both small solid and large open.
