Yuav nrhiav tau ntim ntawm a rectangular prism , muab nws 3 qhov ntev: ntev x dav x qhov siab. Cov ntim yog qhia nyob rau hauv kub units.

Hais txog qhov no, tag nrho cov ntim hauv cubic units ntawm lub prism yog dab tsi?

Koj tuaj yeem muab txhua qhov txiaj ntsig no ua ke kom tau txais ntim ntawm rectangular prism . Cov ntim ntawm rectangular prism yog 10 kub units los yog units 3. Cov units yog kub units vim koj multiplied units 3 zaug thaum koj muab qhov siab, qhov ntev, thiab qhov dav.

Ib sab saum toj no, qhov ntim ntawm lub prism yog dab tsi? Muab qhov ntev, qhov dav, thiab qhov siab. Koj muaj peev xwm muab lawv nyob rau hauv ib qho kev txiav txim kom tau txais cov txiaj ntsig sib txawv. Cov mis rau nrhiav tus ntim ntawm a rectangular prism yog cov hauv qab no: Ntim = Length * Height * Dav, los yog V = L * H * W.

Ib yam li ntawd, nws yog nug, ua li cas koj nrhiav tau ntim hauv cubic units?

Chav ntsuas ntsuas

  1. Volume = ntev x dav x qhov siab.
  2. Koj tsuas yog yuav tsum paub ib sab kom paub qhov ntim ntawm lub voos xwmfab.
  3. Cov ntsuas ntsuas rau ntim yog cubic units.
  4. Volume yog nyob rau hauv peb-dimensions.
  5. Koj tuaj yeem muab cov sab hauv txhua qhov kev txiav txim.
  6. Sab twg koj hu ntev, dav, lossis qhov siab tsis muaj teeb meem.

Qhov ntim ntawm Prism yog dab tsi?

Cov mis rau lub ntim ntawm a prism yog V = Bh, qhov B yog qhov chaw hauv paus thiab h yog qhov siab. Lub hauv paus ntawm prism yog ib daim duab plaub. Qhov ntev ntawm daim duab plaub yog 9 cm thiab qhov dav yog 7 cm. Thaj tsam A ntawm ib daim duab plaub nrog qhov ntev l thiab dav w yog A = lw.
