Kutfutfukiswa kwe-hood yekukhipha

Kutfutfukiswa-kwephethini ye-hood ye-ekzosi ngesimo sephiramidi lencishiwe

X - Ububanzi besisekelo lesiphansi.
Y - Kuphakama kwephiramidi.
F - Budze besisekelo lesingetulu.
E - Bubanti besisekelo lesisetulu.
G - Ubude ubuso eceleni kwephiramidi. I-Apofema.
U - I-angle yekuthambekela kwephiramidi.

Tindlela tekukhokha nge-inthanethi.

I-calculator ikuvumela kutsi ubale imikhawulo yephiramidi lencishiwe ye-tetrahedral lenesisekelo lesiyindilinga. Loku kuyasita ekubaleni ema hood ekukhipha umoya, hood yekhishi noma i barbecue, noma hood yephayiphi ye chimney.

Indlela yekusebentisa sibalo.

Khetsa tilinganiso lapho kubalwa kutawentiwa khona. Niketa tilinganiso letatiwako kanye nema-engeli ephiramidi. Chafata inkinobho letsi Bala. Ngenca yekubalwa, imidvwebo yephethini ye-cap iyakhicitwa.
Lemidvwebo ikhombisa bukhulu betincenye ngamunye wephethini yephiramidi lejutjiwe.
Imidvwebo nayo iyakhicitwa: kubuka ngaphambili kanye nekubuka eceleni.

Uma bukhulu be-E bulingana nebukhulu be-F, kutawuba nephiramidi levamile lejutjiwe.
Uma tilinganiso tingu E = 0 na F = 0, kutawuba nephiramidi levamile.

Ngenca yekubalwa, ungatfola kutsi:

I-angle yekuthambekela kwephiramidi, uma bekungatiwa.
Kusika ema-angle ekuthuthukiseni.
Indzawo lesetulu kanye nato tonkhe tindzawo letiseceleni.
Indzawo lesetulu yesisekelo lesiphansi.
Ivolumu yephiramidi.
Tilinganiso telishidi lemsebenti.

Kunaka. Ungakhohlwa kwengeta tibonelelo temagoco ekuxhumanisa tincenye te-hood.
