Zingaki amalitha e cube

Ukuze siphendule lo mbuzo, kudingeka siqonde imiqondo ezifana "l" futhi "cube". Kodwa kulabo abaqondile ukuqedela ngaphambi kokuphela kwe-athikili, impendulo yombuzo othi "? Zingaki amalitha e cube noma 1 imitha cubic" Kuyoba wakubeka - 1000 amalitha. Manje yonke into ukuze.

Kuyini ilitha? Ilitha - iyunithi yokulinganisa. I Russian Federation has GOST 8.417-2002 ngayo, okubekela isiqu inikeza izincazelo futhi echaza ukuthi ukusebenzisa amayunithi tintfo lucobo. Lowo Mbhalo wangonyaka we libala lisisakhiwo yokukala International amayunithi SI nemikhiqizo yalo. The main uyalandisa imitha. Lena indlela bahamba ukukhanya cleaner isikhathi isikhathi okuyinto ilingana 1/299792458 imizuzwana. Le mithetho esiyifunda endaweni noma ivolumu kulinganiswa amayunithi etholakala: imitha square (m2) kanye imitha cubic (M3). № Ithebula 6 uhlu GOST amayunithi 8.414-2002 akufakiwe uhlelo SI futhi ivumela ukusetshenziswa ngaphandle komkhawulo. Ukuze-SI-non amayunithi osebenza litre (L). Isetshenziselwa nesilinganiso tintfo lucobo ezifana ivolumu noma umthamo. 1 ilitha = 1 dm³ = 10-3 m³. Ngakho, nathi singakwethemba ukubala amalitha amaningi indlela yamanzi cube. Kusukela 1 m kanye equkethwe 10 DM m³ = 1 1 1 • m • m 1 m ke 1 m³ DM = 10 • 10 • 10 DM DM DM = 1000 = 1000 amalitha.

Ngegama elithi "cube" bavela lesiGreki «kybos», isimo sinzima kakhulu, njengoba nje iye nezincazelo eziningana.

1. Bona esiqokiwe umzimba weJiyomethri emelela polyhedron ejwayelekile - geksaeder, ubuso ngamunye (eziyisithupha) isikwele. Uma ohlangothini square ilingana 1 m, kuba umzimba usesikhundleni ivolumu 1 m³ noma 1000 amalitha. Kodwa uma ohlangothini onqenqemeni kuzohluka, isibonelo, 3 m ke umbuzo "Bangaki amalitha e cube?" Impendulo zizohluka. a polyhedron okunjalo usesikhundleni ivolumu 3 m 3 • m • m 3 = 9 = 9000 amalitha m³.
2. I eyayivame "cube" kumelwe kuqondwe njengokusho volume of 1 imitha cubic. Kusetshenziswa, isibonelo, ukulinganisa lemali igodi inhlabathi noma umthamo uketshezi akhishwa. Uma ucela, "Amanzi Cube - bangaki amalitha", kulesi simo, impendulo kulandela kusukela GOST 8.417-2002, ebheka isilinganiso amayunithi, okusho cubic metres amanzi - 1 m³ = 1000 amalitha.
3. Esifundweni sezibalo, igama elithi "cube" libhekisela degree of izinombolo ufuna ukuba azale ande ngokwalo kathathu. Kulokhu, umbuzo "Bangaki amalitha amaningi cube?" Okungalungile.
4. Kwezinye izinqubo yokukhiqiza (isib ukushisa wobunjiniyela, chemical umkhakha) kanye ekhaya igama elithi "cube" ingase isho waphansi lapho uketshezi abilayo ukuze ukuhwamuka noma ziphuzo zazihluzwa (ziphuzo zazihluzwa). Lezi amadivayisi ngokuvamile ube nohlobo yehluke polyhedron ejwayelekile (hexahedron). ngokuvamile cylindrical. Njengoba kulokhu, ukubala ukuthi zingaki amalitha e cube? Ukusebenzisa isilinganiso amayunithi, kubalulekile ukuba azale ande ivolumu eyaziwayo kudivayisi cubic metres ngo-1000, umphumela uyoba umthamo yayo ngamalitha.

Ukuguqula ivolumu, uzwakalise kwezinye amayunithi angakahleleki, ezifana amasentimitha cubic, noma amamilimitha angu amakhilomitha, kufanele ubuyele ku-GOST 8.417-2002. Okuningi ngokunembile, ukuze itafula yayo № 7, lapho imithetho ezichazwe lapha lapho kumiswa izimpawu nezimpinda idesimali futhi submultiples tintfo lucobo ohlelweni SI. Ngenxa yalezi zinjongo aduduze (lapho kuboniswe yizicucu Ithebula 20) lapho sihambisana isici ledesimali. Lapho ukungezwa iyunithi eyisisekelo isiqalo ethile (isib iota, isilwane, Giga, ikhilogremu, emphemeni, Santee, milli nezinye) kuyacaca at idesimali isici ukubaluleka oluyisisekelo Wandisa ukuthola amaningi iyunithi s.

Isiqalo esithi "ikhilo" okuhambelana isici 10³ (noma 1000). "USanti» - 10² (noma 100). "Milli" - 10-³ (noma 1/1000). Njengoba isibonelo, singakwazi ukubala amalitha amaningi indlela ka cube (polyhedra njalo), ohlangothini ubuso okuyinto ilingana 0.3 Kumakhilomitha (km), 3 amasentimitha (cm) noma 3 kwangu (mm).

1. Ngoba icala lokuqala: 0.3 km • 0.3 km • 0.3 km = 0.009 cubic amakhilomitha. Kusukela 1 km = 1000 m, le 0.009 km ³ = 9,000,000 = 9,000,000,000 amalitha m³.
2. Ukuze esimweni sesibili 3 • cm 3 • cm 3 cm = 9 cm ³. Kusukela 1 cm = 1/100 m ke 9 = 0.000009 cm³ m³ = 0,009 amalitha. Ukuze amavolumu enjalo ngokuvamile okusetshenziselwa iyunithi yokukala eyaziwa ngemililitha (ml) 1 cc noma 10-³ l ngayinye.
3. Ngoba icala lesithathu: 3 mm • 3 mm • 3 mm = 9 mm³. Njengoba 1/1000 mm = 1 m, bese 9 mm³ = 0.000000009 = 0.000009 m³ l. Khiqiza yisiphi isinyathelo ngezinombolo ezifana esingesihle, ngakho yokukala, ngokuthi microliter (l), okuyinto 10-³ ml noma 10-6 amalitha.

Kusobala ukuthi ukuze impendulo efanele umbuzo "Bangaki amalitha e cube?" Noma iyiphi amayunithi ukuhunyushwa nesilinganiso ofuna ukuyisebenzisa ejwayelekile kwemibuso GOST 8.417-2002 (yamukelwe emazweni ayishumi - amalungu CIS). Ukuba khona e enamadijithi yakhe ukuqokwa iphuzu kubonisa ukuthi kungokwalabo Metrology (isayensi, okuyinto ebalulekile nesilinganiso ubunye futhi izuzwe ukunemba okunjalo). Ukuze uthole ukwaziswa: amazinga e ekubizweni okuyinto inombolo nambili iphuzu, ihlanganise lokho okufanele ukwenze ukuqinisekisa izimo zokusebenza eziphephile.
