Kodi malita ambiri kyubu ndi

Kuti tiyankhe funso limeneli, tiyenera kumvetsa mfundo monga "L" ndi "kyubu". Koma amene sakufuna kumaliza lisanathe nkhaniyi, yankho la funso "Kodi malita mu kyubu kapena 1 mita kiyubiki ambiri" Kodi kukhala wopezeka - malita 1000. Tsopano chirichonse mu dongosolo.

Kodi lita imodzi? Lita - unit muyeso. Ku Russia ali GOST 8.417-2002, omwe akuti amapereka matanthauzo ndipo limafotokoza mmene ntchito mayunitsi a zedi thupi. Chikalatachi imalemba unit yaikulu ya muyeso wa bungwe la International mayunitsi SI ndi ena ofanana zace. Waukulu anafotokoza mita. Imeneyi ndi njira anayenda ndi kuwala zingalowe kwa nthawi umene uli wofanana masekondi 1/299792458. makhalidwe amenewa, monga dera kapena buku ali anayeza anachokera mayunitsi: mita lalikulu (m2) ndi mita kiyubiki (M3). № Table 6 mndandanda GOST 8.414-2002 mayunitsi sanali m'gulu dongosolo SI Zimathandizanso kuti ntchito popanda malire. Omwe sanali SI mayunitsi likukhudza lita (L). Izo ntchito muyeso wa zedi thupi monga buku kapena mphamvu. 1 lita imodzi = 1 dm³ = 10-3 m³. Choncho, tingathe kuwerengera malita angati madzi kyubu a. Popeza 1 mita ndi zopezeka 10 DM m³ = 1 1 1 • mamita • mamita 1 m, ndiye 1 m³ DM = 10 • 10 • 10 DM DM DM = 1000 = 1000 malita.

Ndi mawu akuti "kyubu", anachokera ku Greek «kybos», zinthu zovuta kwambiri, ngati iwo ali matanthauzo ambiri.

1. Iwo anasankha thupi zojambula woimira polyhedron zonse - geksaeder, aliyense nkhope (a sikisi) ndi mbali zinayi zofanana. Ngati mbali ya lalikulu ndi wofanana 1 m, ndi thupi ali ndi buku la 1 m³ kapena malita 1000. Koma ngati mbali m'mphepete adzakhala osiyana Mwachitsanzo, 3 m, ndiye funso "Kodi malita ambiri kyubu bwanji?" Yankho adzakhala osiyana. Chotero polyhedron ndi ali ndi buku la 3 mamita 3 • mamita • mamita 3 = 9 = 9000 m³ malita.
2. The colloquial "kyubu" bwino monga buku la mita kiyubiki 1. Ntchito Mwachitsanzo, chaka kuchuluka zakale dothi kapena buku la madzimadzi amawapopa. Ngati mudzapempha, "Madzi kyubu - angati malita", mu nkhani iyi, yankho motere kuchokera GOST 8.417-2002, amene amasankha chiŵerengero mayunitsi, mwachitsanzo kiyubiki mamita wa madzi - 1 m³ = 1000 malita.
3. Mu masamu, mawu akuti "kyubu" amatanthauza mlingo wa chiwerengero mukufuna kuchulukitsa palokha katatu. Pankhaniyi, funso "Kodi malita ambiri kyubu?" Zosayenera.
4. Mu njira zina opanga (mwachitsanzo, kutentha mphamvu zomangamanga, mafakitale mankhwala) ndi mawu kunyumba "kyubu" Angatanthauze ndi zida zimene madzi otentha kuti evaporation kapena distillation (distillation). zipangizozi zambiri nawo mawonekedwe osiyana ndi polyhedron zonse (hexahedron). iwo amakhala cylindrical. Monga mu nkhani iyi, kuwerengera angati malita mu kyubu ndi? Kugwiritsa chiŵerengero mayunitsi, m'pofunika kuchulukitsa buku kudziwika kwa chipangizo mu kiyubiki mamita ndi 1000, ndipo zotsatira zake zidzakhala buku zake malita.

Kutembenuza buku, m'kukoma mayunitsi ena a muyeso, monga masentimita kiyubiki, kapena millimeters makilomita, tiyenera kubwerera ku GOST 8.417-2002. More ndendende, kuti patebulo pake № 7, mmene malamulo amene akutchulidwa pano ndi mapangidwe zizindikiro ndi multiples decimal ndi submultiples wa zedi thupi mu dongosolo SI. Pakuti zolinga zimenezi mtima (pali anasonyeza mu zidutswa Table 20) omwe akufanana ndi chinthu decimal. Pamene anawaonjezera unit zofunika kwa manambala oyambirira makamaka (mwachitsanzo, dontho, mphaka, giga, kilo, sitimayo, Santee, milli ndi zina) zimaonekeratu pa ena decimal chinthu mtengo zoyambirira zikuchulukireni kupeza angapo wagawo m.

Ndi manambala oyambirira "kilo" limafanana chinthu 10³ (kapena 1000). "Santi» - 10² (kapena 100). "Milli" - 10 ³ (kapena 1/1000). Mwachitsanzo, tingathe kuwerengera malita angati a kyubu (zonse polyhedra), mbali nkhope za amene ali wofanana makilomita 0,3 (km), 3 masentimita (cm) kapena 3 millimeters (mm).

1. Pakuti yoyamba: 0,3 Km • 0,3 Km • 0,3 Km = 0.009 makilomita kiyubiki. Popeza 1 Km = 1000 m, ndi 0.009 Km ³ = 9,000,000 = 9,000,000,000 malita m³.
2. Pakuti nkhani yachiwiri 3 • masentimita 3 • masentimita 3 cm = 9 masentimita ³. Popeza 1 cm = 1/100 m, ndiye 9 = 0.000009 m³ cm³ = 0,009 malita. Chifukwa mabuku amenewa amagwiritsidwa ntchito unit wa muyeso kudziwika pa milliliter (ml) ya 1 CC kapena 10 ³ L.
3. Pakuti nkhani lachitatu: 3 mamilimita • 3 mamilimita • 3 mamilimita = 9 mm³. Popeza 1/1000 mamilimita = 1 m, ndiye 9 mm³ = 0.000000009 = 0.000009 m³ L. Ndisonyezeni kanthu ndi manambala ngati kovuta, kotero unit wa muyeso, otchedwa microliter (l), chimene chiri 10 ³ ml ya kapena malita 10-6.

N'zoonekeratu kuti yankho leni-leni funso "Kodi malita ambiri kyubu?" Kapena mayunitsi lililonse limene analimasulira muyeso mukufuna kugwiritsa ntchito Interstate muyezo GOST 8.417-2002 (kuvomerezedwa ndi maiko khumi - mamembala CIS). Pamaso pa eyiti manambala lake lakuti ndi mfundo limasonyeza kuti adzaupereka kwa metrology (sayansi, imene n'kofunika umodzi muyeso ndipo zimatheka molondola chofunika). Kuti mudziwe: miyezo mu chikhazikitso cha zomwe ndi chiwerengero khumi ndi mfundo, monga amafuna kuonetsetsa otetezeka ntchito.
