Sedjibeke (shaxan)

Sedjibeke ama Saddexjibaarane (af-ingiriis: cube) Waxa uu leeyahay 6 dhinac oo isku beegan, 12 gees, 8 xagal dhamaantoodna dhinac kasta waa qaab labajibaaren ah, Xaglahiisuna waa kuwa quman, Balacyada oo dhanna waa isla egyihiin.

Mugga saddexjibbaarane waxaa lagu helaa adigoo isku dhufta : $d^{3}=d\cdot d\cdot d$

Qaacidada

Seddex jibaarnaha waxaa loo eegaa geesaha inta ay isku jiraan d,

Bedka	$6d^{2}\,$
Mugga	$d^{3}\,$
Isku beegnaanta xarriiqda	${\sqrt {2}}d$
Firaaqada isgoosyada	${\sqrt {3}}d$
Dhexroorka kagac Goobo	${\frac {\sqrt {3}}{2}}d$
Goobo gacan keeda taabanaya dhinacyada oo dhan	${\frac {d}{\sqrt {2}}}$
Kubad taabaneeysa dhamaan dhiancyada	${\frac {d}{2}}$
Xaglo isku dhafan	${\frac {\pi }{2}}$
