Izibali zomthamo

Esi sikhaltyhuleyitha esibala ngokukodwa umthamo we-cuboid, i-metric yenkxaso kunye neeyunithi zobukhosi (ii-intshi, iinyawo, iiyadi, mm, i-cm okanye imitha), kunye nesiphumo sevolumu sinokuguqulela kwiyunithi eyahlukileyo, kunye nefomula yokubala kunye netyhubhu ebonakalayo eguqukayo, isinceda ukuba sifumane iimpendulo kwaye siqonde iziphumo ngokulula.

Usisebenzisa njani esi sikhalityhuleyitha ?

  1. Faka amanani kwizikhewu zobude, ububanzi kunye nobude
  2. Yamkela idecimals okanye iqhezu, umz. 2.6, 7.8, 4 1/2 okanye 3/5
  3. Khetha iyunithi yomlinganiselo owusebenzisayo (ku, ft, yd, mm, cm, m)
  4. Khetha iyunithi yesiphumo oyithandayo
  5. Iya kubala ngokuzenzekelayo iziphumo kwaye iphendule ngokusebenzisana.
  6. Isiphumo sokubala siya kujikelezwa.

Indlela yokubala umthamo we-cuboid

ICuboid yibhokisi eyomeleleyo enomphezulu wawo wonke uxande lommandla omnye okanye iindawo ezahlukeneyo.
Ikubhidi iya kuba nobude, ububanzi, nokuphakama.

Umthamo we cuboid = (ubude × ububanzi × ubude) cubic units.

Ifomula yoMqulu weRectangle

Umthamo = ubude × ububanzi × ubude

Umzekelo wokubala

Fumana umthamo we-cuboid yemilinganiselo ye-14 cm × 12 cm × 8 cm.

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

Ukuba sifuna ukuguqula iiyunithi zevolumu zibe ziiyunithi ezahlukeneyo, sinokuguqula iiyunithi zobungakanani ukuba zibe kwivolumu efanayo kuqala,
umzekelo,
ityhubhu inemilinganiselo ye-12.5 phakathi, i-14 phakathi kunye ne-9.3 ngaphakathi.
Ingaba ithini ivolyum kwi-ft³?

12.5 phakathi = 12.5 ÷ 12 ft = 1.042 ft
14 kwi = 14 ÷ 12 ft = 1.167 ft
9.3 kwi = 9.3 ÷ 12 ft = 0.775 ft
1.042 × 1.167 × 0.775 phakathi = 0.94241085 ft³
emva kokusondeza, ivolyum yi-0.94 kwi-ft³

Cuboid kunye neCube

Acuboidyinto emile okwebhokisi. Inobuso obuthandathu obusicaba kwaye zonke ii-engile ziziengile ezichanekileyo. Kwaye bonke ubuso bayo buxande. Ikwayiprism kuba inecandelo elinqamlezayo elifanayo ngobude. Enyanisweni yiprism yoxande.

Xa bobathathu ubude bulingana bubizwa ngokuba ngu-aityhubhu(okanye ihexahedron) kwaye ubuso ngamnye busisikwere. Ityhubhu iseyiprism kwaye ikwayicuboid.
