Indlela yokufumana ivolyum bhokisi?

Phambi kokuba ugqithele ngakwicala lokwenziwa komsebenzi nqaku, apho siza kukhangela umthamo kwebhokisi, masikhumbule ukuba lo mfanekiso, uze ufunde kutheni ezi zibalo ukuze kufuneka.

Kukho iinkcaza ezintathu, baze ke bonke alingana. Ngokomzekelo, omnye parallelepiped ngu:

1. emacala ezinobuso ezintandathu, iyileyo a parallelogram.

2. ntandathu, nto leyo eye izibini ezintathu ubuso ngaxeshanye kunye nabanye.

3. Le bemilo wakhe isiseko kuyinto parallelogram.

Kakhulu mhlawumbi eqhelekileyo kwiintlobo ebomini bethu phantsi ingqalelo kweemilo zejiyometri - a cuboid kunye ityhubhu. Ukongeza, i-umahluko phakathi parallelepiped ngqo kunye elibhalwe ngokumileyo.

Cuboid: volume

Cuboid ezahlukeneyo kukuba ngamnye thi - ukuba loo uxande. Njengoko umzekelo indlu le ndlela kungakhokelela ibhokisi yesiqhelo (a yezihlangu, isipho, nokuposwa).

Okokuqala kufuneka ukufumana amaxabiso macala omabini esisekweni parallelepiped, leyo zicwangciswe aa Incopho na omnye komnye (kwi-moya Bambiza ububanzi nobude).

P = A * B, apho A - ubude B - ububanzi.

Ngoku senze enye nomlinganiselo - ukuphakama isafobe onikiweyo, eziya kubizwa ngokuba N.

Kodwa ke imali efunekayo sifunda, ukuba zande ukuphakama ukuya kwindawo isiseko, oko kukuthi:

V = n * H.

Umthamo we ibhokisi ngqo

parallelepiped ngqo ungachazwa ukuba ecaleni iinkalo bakhe - amaxande ngenxa yokuba ukuba nkqo ngokomfanekiso kwisiseko.

Lo mqulu ibalwa ngokufanayo, umahluko kuphela kukuba ephakamileyo apha - hayi kukho emphethweni ebhokisini. Kule meko ke umgca esithungelanayo ubuso ezimbini elichasayo nkqo ngokomfanekiso kunye nesiseko saso.

Kuseloko lasekwayo parallelepiped wenu parallelogram kunokuba uxande, ngoko ifomula ukuze kubalwe le ndawo isiseko thile inzima. ngoku uya kukhangela ngale ndlela:

P = A * B * isono (a) kuyo A, B - ubude yaye, ngokunjalo, ububanzi isiseko, kwaye "a" - ikona leyo zakha kwikona zabo.

Indlela ukufumana umthamo a elibhalwe ngokumileyo yoxande?

Izidanga, wabona nayiphi parallelepiped, nto leyo tye.

Ngenxa yokuba ubuso amanani ayikho nkqo kwi siseko, kufuneka kuqala ufumane ukuphakama. Phinda phezu ubukho efanayo (jonga ngentla ifomula), kwaye ufumane umyinge:

V = P H *, apho P - indawo isiseko, H - ukuphakama.

Umthamo we parallelepiped ngobuso square

Cube - yinto parallelepiped eziziingxande, ubuso nganye ezintandathu isikwere. Ngenxa yoko impahla mzobo - zonke Iikona ayo ngokulinganayo phakathi kwabo. Ngokomzekelo, cinga yokudlala umntwana neetyhubhu.

Kaloku, zonke ukufumana kakhulu nje umthamo wento enamacala. Ukuze wenze oku, kufuneka wenze umlinganiselo omnye kuphela (ubambo) nokwakha ixabiso afunyenwe kwi isidanga wesithathu. Nantsi indlela yokwenjenjalo:

V = A³.

Njengokuba umthamo bhokisi kunokuba luncedo kuthi ebomini bethu?

Sicinga ukuba sele axakwe ngale ngxaki, njengoko inani leebhokisi abanokufakwa yomqeshi yemoto yakho. Ukuze wenze oku, kufuneka ukuba bakwazi ukuzixhobisa nomlawuli okanye iteyiphu, usiba, iphepha, kwakunye iifomyula ngentla yokubala umthamo a cuboid.

Ngokulinganisa nomthamo ibhokisi, kwaye phinda ixabiso ngenani lezakhelo zakho ezikhoyo, uza kufunda kufuneka zingaphi cc iisentimitha na ukuba ngokuzibeka yomqeshi emotweni.

Kwaye ewe, khumbula ukuba kwezinye iimeko, kucetyiswa ukuba iisentimitha cubic uya kuguqulwa ube leemitha. Ngoko ke, xa ngenxa ufumana umthamo ibhokisi-50 cube cm, ngoko ukudlulisela phinda eli nani nge 0,001. Ngoko ke ufumana imitha cubic. Kwaye ukuba ufuna ukwazi ivolyum iilitha, okufumeneyo cubic metres, phinda ngo-1000.
