Sedjibeke (shaxan)

saddexjibbaarane

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 :$d^{3}=d\cdot d\cdot d$
