| Cov duab | Formula | Hloov pauv |
| Txoj cai Rectangular Prism | V = LWH | L yog qhov ntev, W yog qhov dav thiab H yog qhov siab. |
| Prism los yog lub tog raj kheej | V = Aw | A yog thaj tsam ntawm lub hauv paus, h yog qhov siab. |
| Pyramid los yog Cone | V = 13 Aw | A yog thaj tsam ntawm lub hauv paus, h yog qhov siab. |
Tsis tas li ntawd, koj piav qhia qhov ntim li cas? Ntim hais txog tus nqi ntawm qhov chaw qhov khoom siv. Hauv lwm lo lus, ntim yog ib qho kev ntsuas ntawm qhov loj ntawm qhov khoom, ib yam li qhov siab thiab qhov dav yog txoj hauv kev los piav txog qhov loj. Yog tias qhov khoom yog hollow (hauv lwm lo lus, khoob), ntim yog cov dej uas nws tuav tau. Sim ua qhov no hauv tsev: Nqa ib khob loj thiab khob me me.
