Cov mis rau ntsuas ntim yog qhov siab x dav x ntev. Hais, piv txwv li, koj xav ntsuas qhov ntim ntawm koj lub pas dej da dej. Koj pom tias nws ntsuas 2 meters tob (height), 10 meters dav thiab 12 meters ntev. Yuav nrhiav tau kub m , koj ntau Luas = 2 x 10 x 12 = 240 kub m.
Tsis tas li ntawd, koj yuav suav li cas cubic meters?
Qhov cubic meter formula rau txawv units
- Length (meter) x dav (meter) x qhov siab (meter) = cubic meters(m³)
- Luas (cm) x dav (cm) x qhov siab (cm) / 1, 000, 000 = cubic meters.
- Length (mm) x dav (mm) x qhov siab (mm) / 1, 000, 000, 000 = cubic meters.
Qhov thib ob, koj yuav suav li cas cubic meters ntawm pob zeb? Pob zeb Ntim Kev suav . 1 kub meter (1m3) tuaj yeem pom los ntawm kos lub voos xwmfab 1 meter luas x 1 meter loj x1 meter qhov tob. Rau xam tus pob zeb ntim a pob zeb slab koj muab qhov ntev, dav thiab qhov tob ntawm qhov pob zeb slab kom tau txais kev kwv yees ntawm tus nqi ntawm pob zeb koj xav tau hauv kub ib m3m.
Ib yam li ntawd, nws tau nug, Kuv yuav hloov cov square meters rau cubic meters li cas?
Piv txwv li, yog tias koj paub cov square thaj tsam ntawm ib sab ntawm a kub thiab cov kub qhov siab, koj tuaj yeem nrhiav tau kub thaj tsam los ntawm hloov dua siab tshiab los ntawm meters square rau meters kub. Muab qhov ntev ntawm thaj chaw los ntawm nws qhov dav. Qhov no yuav muab rau koj square meters.
Ib tus cubic meter yuav muab ntau npaum li cas?
Lub cube no yog lub cube zoo meej. Qhov ntev, dav thiab qhov siab yog tib yam: 1 meter . (Ib meter yog sib npaug li ntawm 3.28 ko taw, uas yog me ntsis ntev dua ib lub yardstick koj yuav pom hauv koj chav kawm.) kub meter yog 1 meter ntawm txhua sab.

Yuav ua li cas koj pom lub kaum sab xis nruab nrab muab qhov chaw thiab lub vojvoog ntawm ib lub sector?
Kev txiav txim siab Central Angle Los ntawm Sector Area (πr2) × (central angle in degrees ÷ 360 degrees) = sector area. Yog hais tias lub hauv paus lub kaum sab xis ntsuas nyob rau hauv radians, lub mis hloov mus ua: sector cheeb tsam = r2 × (central kaum hauv radians ÷ 2). (θ ÷ 360 degree) × πr2. (52.3 ÷ 100π) × 360. (52.3 ÷ 314) × 360
Yuav ua li cas koj pom qhov ntim hauv cubic units?
Chav ntsuas Volume = ntev x dav x qhov siab. Koj tsuas yog yuav tsum paub ib sab kom paub qhov ntim ntawm lub voos xwmfab. Cov ntsuas ntsuas rau ntim yog cubic units. Volume yog nyob rau hauv peb-dimensions. Koj tuaj yeem muab cov sab hauv txhua qhov kev txiav txim. Sab twg koj hu ntev, dav, lossis qhov siab tsis muaj teeb meem
Yuav ua li cas hloov txoj kab uas hla mus square meters?
Piv txwv li, peb muaj thaj tsam ntawm 303,000 square meters. Faib thaj tsam (hauv square units) los ntawm Pi (kwv yees li 3.14159). Piv txwv li: 303,000/3.14159 = 96447.98. Siv lub hauv paus square ntawm qhov tshwm sim (Piv txwv: 310.56). Qhov no yog lub vojvoog. Tam sim no muab ob npaug rau lub vojvoog kom tau txoj kab uas hla (Piv txwv: 621.12 meters)
Yuav ua li cas koj hloov ntaub hnyav rau meters?
Fabric ntev yog 1700 meters. Npuag dav = 72 nti hloov nws mus rau hauv meters = (72 * 2.54) / 100 = 1.83 meters. Npuag GSM = 230 grams
Yuav ua li cas tshwm sim thaum koj muab cov khoom them nqi ze ntawm Electroscope thiab vim li cas?
Hauv cov txheej txheem induction ntawm kev them nyiaj, ib qho khoom them raug coj los ze rau tab sis tsis kov lub electroscope. Qhov no tau piav qhia los ntawm cov kev them nqi zoo li lub hauv paus ntsiab lus. Lub zais pa uas tsis zoo tiv thaiv cov hluav taws xob tsis zoo, yog li yuam kom lawv txav mus los
