Kutsvaga huwandu hweprism: fomula uye mabasa

Muchinyorwa chino, tichatarisa kuti ungawana sei vhoriyamu yeprism uye ongorora mienzaniso yekugadzirisa matambudziko kugadzirisa zvinhu.

Iyo formula yekuverenga huwandu hweprism

Huwandu hweprism hwakaenzana nechigadzirwa chenzvimbo yechigadziko chayo uye kureba kwayo.

V=S_kuru ⋅ h

• S_kuru - nzvimbo yepasi, kureva kwatiri, quadrilateral ABCD or EFGH (yakaenzana kune mumwe nemumwe);
• h ndiko kureba kweprism.

Iyo fomula iri pamusoro inokodzera anotevera marudzi emaprism: 

• yakatwasuka - mbabvu dzeparutivi dziri perpendicular kune chigadziko;
• yakarurama - prism yakananga, iyo nheyo iyo inogara polygon;
• akarerekera - mbabvu dzeparutivi dziri pakona neruremekedzo kune hwaro.

Mienzaniso yemabasa

Basa 1

Tsvaga huwandu hweprism kana ichizivikanwa kuti nzvimbo yechigadziko chayo ndeye 14 cm²uye kureba i6 cm.

Sarudzo:

Isu tinotsiva izvo zvinozivikanwa kukosha mufomula uye titore:

V = 14cm² ⋅ 6 masendimita = 84 cm³.

Basa 2

Kureba kweprism ndeye 106 cm³. Tsvaga kureba kwayo kana ichizivikanwa kuti nzvimbo yechigadziko ndeye 10 cm².

Sarudzo:

Kubva pane fomula yekuverenga vhoriyamu, zvinotevera kuti kureba kwakaenzana nevhoriyamu yakakamurwa nenzvimbo yeuXNUMXbuXNUMXbthe base:

h = V / S_kuru = 106 masendimita³ / 10cm² = 10,6cm.
