Iyi ni calculatrice ibara byumwihariko ingano ya cuboid, ishyigikira ibipimo bya metero nubwami (santimetero, ibirenge, imbuga, mm, cm cyangwa metero), kandi ibisubizo byijwi birashobora guhinduka mubice bitandukanye, hamwe na formula yo kubara hamwe na cube igaragara, idufasha kubona ibisubizo no kumva ibisubizo byoroshye.
Cuboid ni agasanduku gakomeye buri buso ni urukiramende rw'akarere kamwe cyangwa ahantu hatandukanye.
Kuboide izaba ifite uburebure, ubugari n'uburebure.
Umubare wa cuboid = (uburebure × ubugari × uburebure) kubice.
Shakisha ingano ya cuboid yubunini 14 cm × 12 cm × 8 cm.
Niba dushaka guhindura ibice byijwi mubice bitandukanye, turashobora guhindura ibice byubunini kugeza mubunini bwa mbere,
urugero,
cube ifite ibipimo bya 12.5 muri, 14 muri na 9.3 muri.
Ni ubuhe bunini muri ft³?
A.cuboidni agasanduku kameze nk'ikintu. Ifite amasura atandatu kandi impande zose ni inguni iburyo. Kandi mumaso yacyo yose ni urukiramende. Nibisanzwe kandi kuko bifite ibice bimwe byambukiranya uburebure. Mubyukuri ni prism y'urukiramende.
Iyo uburebure uko ari butatu buringaniye bwitwa acube(cyangwa hexahedron) kandi buri sura ni kare. Cube iracyari prism kandi nayo cuboid.
