Umthamo wokubala we-cuboid

* * =

Izibali zevolumu

Oz kuye ml(guqula ama-ounces amanzi abe ngamamililitha)
Umthamo wokubala we-cuboid: bala ivolumu yeprism engunxande
Ivolumu yesibali se-sphere: bala ivolumu ye-sphere

Lesi isibali esibala ngokuqondile ivolumu ye-cuboid, i-metric yokusekela kanye namayunithi ombuso (amayintshi, izinyawo, amayadi, mm, cm noma imitha), futhi umphumela wevolumu ungaguqulela kuyunithi ehlukile, ngefomula yokubala kanye nekhiyubhu ebonakalayo eguqukayo, isisiza ukuthi sithole izimpendulo futhi siqonde imiphumela kalula.

Isetshenziswa kanjani lesi sibali?

Faka izinombolo ezikhaleni zobude, ububanzi nobude
Yamukela amadesimali okufakwayo noma ingxenyenamba, isb. 2.6, 7.8, 4 1/2 noma 3/5
Khetha iyunithi yesilinganiso oyisebenzisayo (ku, ft, yd, mm, cm, m)
Khetha iyunithi yomphumela oyithandayo
Izobala ngokuzenzakalelayo imiphumela futhi isabele ngokuhlanganyela.
Umphumela wokubala uzofinyezwa.

Indlela yokubala umthamo we-cuboid

I-Cuboid iyibhokisi eliqinile lapho yonke indawo yayo ingunxande wendawo efanayo noma izindawo ezihlukene.
I-cuboid iyoba nobude, ububanzi nokuphakama.

Umthamo we-cuboid = (ubude × ububanzi × ukuphakama) amayunithi ayi-cubic.

Ifomula yevolumu yonxande

Ivolumu = ubude × ububanzi × ukuphakama

Isibonelo sokubala

Thola ivolumu ye-cuboid yobukhulu obuyi-14 cm × 12 cm × 8 cm.
Volume of cuboid ?

14 × 12 × 8 cubic cm.
= 1344 cubic cm.
Ngakho-ke, umthamo we-cuboid = 1344 cubic cm.

Uma sifuna ukuguqula amayunithi evolumu abe amayunithi ahlukene, singaguqula amayunithi obukhulu abe afanayo wevolumu kuqala,
Ngokwesibonelo,
ikhyubhu inobukhulu obungu-12.5 in, 14 in no-9.3 in.
Ingakanani ivolumu ku-ft³?

12.5 ku = 12.5 ÷ 12 ft = 1.042 ft
14 ku = 14 ÷ 12 ft = 1.167 ft
9.3 ku = 9.3 ÷ 12 ft = 0.775 ft
1.042 × 1.167 × 0.775 ku = 0.94241085 ft³
ngemva kokufinyezwa, ivolumu ingu-0.94 ku-ft³

Cuboid futhi Cube

Acuboidkuyinto emise okwebhokisi. Inobuso obuyisicaba obuyisithupha futhi wonke ama-engeli angama-engeli angakwesokudla. Futhi bonke ubuso bayo bangonxande. Iphinde ibe yi-prism ngoba ine-cross-section efanayo ngobude. Eqinisweni iyiprism engunxande.

Uma bobathathu ubude bulingana bubizwa ngokuthi aikhiyubhu(noma i-hexahedron) futhi ubuso obunye buyisikwele. I-cube iseyi-prism futhi iphinde ibe yi-cuboid.
