<<SNAFU is an acronym for the sarcastic expression Situation Normal: All Fucked Up. The acronym is believed to have originated in the United States Marine Corps during World War II.>>

<<The collapse of the [c. 2600 BCE] pyramid at Meidum of SNEFERU is the likely reason for the change from 54° to 43° degrees of SNEFERU's second pyramid at Dahshur, the [c. 2600] Bent Pyramid. SNEFERU's [c. 2580 BCE] Red Pyramid was built at the same shallow 43 degree angle as the upper section of the Bent Pyramid.>>
-------------------------------------------------------------
The [c. 2560] Pyramid of Khufu had a more respectable slope angle of 51.84°.
1.0005 x pi = 3.14317 = 2/tan(51.84°)
.................................................................
The largest possible pyramid for a given amount of very expensive white
"casing stones" has a [octahedron] slope of 54°44′8″ = arctan(sqrt(2)). The [c. 2530] Pyramid of Khafre comes quite close to this with a slope angle of 53° 13'.
.................................................................
The best Egyption [1850 BC] estimate for pi was 256/81
1.0060 x pi = 256/81 ≈ 3.16049
