Whereas cov qauv yooj yim rau thaj tsam ntawm cov duab plaub yog qhov ntev × dav, cov qauv yooj yim rau ntim yog length × width × height.
Koj pom qhov ntim ntawm thaj chaw li cas?
ntim yog qhov ntsuas ntawm qhov muaj peev xwm thiab ntsuas hauv cubic units. Txhawm rau xam qhov ntim ntawm ib lub prism, muab thaj tsam ntawm lub hauv paus (ntev × dav) zaug qhov siab.
Kuv yuav suav thaj tsam li cas?
Thaj tsam yog xam los ntawm kev muab qhov ntev ntawm ib daim duab los ntawm nws qhov dav. Hauv qhov no, peb tuaj yeem ua haujlwm tawm ntawm thaj tsam ntawm daim duab plaub no txawm tias nws tsis yog ntawm daim ntawv squared, tsuas yog ua haujlwm tawm 5cm x 5cm=25cm² (cov duab tsis yog kos rau nplai).
Koj suav qhov ntim thiab thaj chaw li cas?
Nws muab qhov kev faib ua feem ntawm thaj chaw ntawm ib chav tsev ntim ntawm cov khoom (piv txwv li, kheej kheej, lub tog raj kheej, thiab lwm yam). Yog li ntawd, cov qauv los xam qhov chaw ntawm qhov chaw rau qhov ntim piv yog: SA / VOL=thaj chaw saum npoo (x 2) / ntim (x 3) SA/VOL=x-1, qhov twg x yog chav ntsuas.
Cov mis ntawm ntim yog dab tsi?
Whereas cov qauv yooj yim rau thaj tsam ntawm cov duab plaub yog qhov ntev × dav, cov qauv yooj yim rau ntim yog length × width × height.
