txhawm rau nrhiav thaj chaw saum npoo ntawm lub cuboid, ntxiv cov cheeb tsam ntawm tag nrho 6 lub ntsej muag. Peb tseem tuaj yeem sau qhov ntev (l), dav (w), thiab qhov siab (h) ntawm lub prism thiab siv tus qauv, SA=2lw + 2lh + 2hw, txhawm rau nrhiav qhov chaw thaj chaw.
Dab tsi yog thaj chaw ntawm cuboid Chav Kawm 9?
⇒Surface Area of Cuboid= 2(l × b) + 2(b × h) + 2(l × h).
Koj pom thaj chaw saum npoo av thiab qhov ntim ntawm lub cuboid li cas?
Volume of cuboid (V)= length × breadth × area × height.
Yuav ua li cas koj pom thaj tsam ntawm lub cuboid?
thaj tsam ntawm ib lub cuboid tuaj yeem xam los ntawm ntxiv ua ke ntawm thaj tsam ntawm 6 lub ntsej muag. Lub ntsej muag rov qab ntawm lub cuboid yog cov duab plaub sib npaug, yog li nrhiav tag nrho thaj chaw ntawm peb lub ntsej muag sib txawv, tom qab ntawd muab ob npaug rau nrhiav thaj tsam tag nrho.
piv txwv ntawm cuboid yog dab tsi?
Piv txwv ntawm Cuboid
Nws yog ib qho duab peb sab nrog ntev, dav, thiab qhov siab. Piv txwv xws li: Lub thawv noj su . Bricks.
