Yadda za a sami ƙara da wani shigen sukari a cikin hanyoyi daban-daban

Idan muka kwatanta da saba yara tubalan, shi ne mai sauki fahimta da yadda za a sami ƙara da wani shigen sukari. By al'amurra da girma na wani shigen sukari na wani cubic girma gwargwado, misali, da cubic decimeter, mun fara gina daya manyan shigen sukari. Nadawa farko square "kasa", kamar 4x4, ya kamata ka sa 4 more "kasa" to duk gefuna da mu shigen sukari ne daidai. Daidaitan duk bangarorin na shigen sukari - shi ne babban mulki, wanda ya tabbatar da cewa a gaban mu ne wani shigen sukari.

Nemo size of daya square fuska sauƙi, muna bukatar kawai ninka da fadi da tsawon na da tushe, cewa shi ne, don gina wani gefen a cikin square. Tun da muka samu a 'yan layuka - "benaye", ko kuma wajen, su jũya a jere an daidaita adadin zuwa gefen shigen sukari, sakamakon square sake ta tara da tsawo daga cikin shigen sukari, wato, a kan ta gefe. Sai dai itace, saboda haka, cewa mun gina haƙarƙari a cikin na uku mataki, a cikin wasu kalmomi - a wani shigen sukari. Kamar cewa, ta bayyana, sami ƙara da wani shigen sukari!

Shi ne daga nan kuma daukan da sunan da daga yi na uku ikon - "a wani shigen sukari." Wannan shi ne, "da shigen sukari" daukan sau uku a ninka adadin da kanta - da magana da kanta riga yana da asali a cikin gano da mafita ga matsalar da cubic girma.

Amma idan da girman da shigen sukari gefuna, cewa shi ne, a gefe daya na shigen sukari, shi ne ba a sani ba, amma ba da girman da daya daga cikin fuskokin ne yadda za a sami ƙara da wani shigen sukari? Za a yi? Sai dai itace cewa shi ne quite computable.

Diagonal gefen dole lissafi da shugabanci na wannan fuska darajar da kuma sanya shi a cikin wani shigen sukari, da yake a cikin na uku mataki. Don yin shi bayarda, mu zana daya daga cikin cubic fuskoki - shi zai zama murabba'i, misali, PMNK, inda MN - diagonal, wanda aka sani a gare mu. Amfani da Pythagorean Theorem, vozvedom san darajar diagonally a wani square ko a karo na biyu digiri. A wani dama alwatika PMN MN gefe ne hypotenuse, kuma ta square ne daidai da Naira Miliyan Xari da sauran bangarorin biyu, gina a cikin square.

Amma mu sani cewa kafafu - a gefen square fuskar shigen sukari. Saboda haka sakamakon ya kamata a kasu kashi biyu, da kuma samun da square tushen. Wannan sakamakon zai zama daidai ga gefen - gefuna da shigen sukari. Yanzu, abin tambaya shi ne yadda za a lissafta da girma na wani shigen sukari an warware a cikin sauki hanyar. Kamar wani abu kawai kafa gefe na shigen sukari a cikin na uku mataki - da kuma sakamakon a bayyane yake.

Yana yakan faru ne cewa a cikin matsala akwai wani darajar, kamar yadda yankin na daya daga cikin fuskokin da shigen sukari. A wannan yanayin, da farko kana bukatar ka sami gefen square - fuskar shigen sukari. Yana isa ya sami square tushen wurin da aka bayar. Sa'an nan, da lasafta darajar da aka yawaita da aka sani gab yankin.

Wani lokaci za ka kawai bukatar mu san yadda za a sami ƙara da wani shigen sukari, amma akwai wani size, babu hakarkarinsa, babu yankin shigen sukari hannunka. Duk da haka, idan wannan aikin ya bayar da bayanai, kamar yawa da nauyi, da rahoton iya lissafta ta halitta da data darajar: yawa da taro. Neman girma za a iya samu a cikin samfurin.

Kuma idan wani mutum ba ya dauke da wani ma'aunai na yadda za a ci gaba a cikin wannan hali? A aikace, sau da yawa amfani da irin wannan sauki liyafar, a matsayin nutsewa cikin jiki a cikin wani ruwa. Saboda haka yadda za a sami ƙara da wani shigen sukari ba tare da wani tef matakan da shugabanni?

Kana bukatar ka auna daga wani adadin na ruwa a cikin tanki, misali, a cikin kwanon rufi, ciko shi fal. Sa'an nan ya zo da damar sa a wani kwano. Baftisma da shigen sukari a cikin wani ruwa, shi wajibi ne a yi kokarin tattara dukan ruwa slopping kan. Sa'an nan, aunawa beaker ko ta bankuna (dangane da ƙara na shigen sukari dabi'u), za ka iya yin ƙarshe game da ƙarar da wani shigen sukari - shi zai zama daidai da adadin m cewa shigen sukari ya maye gurbin da ya nutse.

Abin takaici, shi ne wuya ko ba zai yiwu ba don auna a cikin wannan hanya da girma na babba size cubes. Amma tun da za ka iya koyi da ba kawai da ƙara na shigen sukari, amma abubuwa da wani siffar.

Akwai sauran yiwuwa na gano da girma na cubes. Alal misali, a da aka sani tsawon na diagonal na wani shigen sukari (ba gefen!). An sani cewa dabara na shigen sukari diagonal bayyana samfur na gefuna da square tushen na 3. Saboda haka, diagonal raba ta da square tushen na 3 da kuma samu gefen tsawon. Bayan da cewa, duk abin da mai sauki ne: kafa sakamakon a wani shigen sukari da kuma samun ake so mayar da martani.
