Ngā tātai rōrahi

He tātaitai tenei e tatau ana i te rōrahi o te pūtoru, ine tautoko me te wae imperial (inihi, waewae, iari, mm, cm, mita ranei), ka huri te hua rōrahi ki te waeine rerekē, me te tātai tātai me te mataono hihiko. ka awhina i a maatau ki te tiki whakautu me te maarama ngawari ki nga hua.

Me pehea te whakamahi i tenei tatauranga?

  1. Whakauruhia nga tau ki nga waahi o te roa, te whanui me te teitei
  2. Whakaaetia te whakaurunga ira, hautau ranei, hei tauira. 2.6, 7.8, 4 1/2, 3/5 ranei
  3. Kōwhirihia te waeine ine e whakamahia ana e koe (in, ft, yd, mm, cm, m)
  4. Kōwhirihia te waeine hua e hiahia ana koe
  5. Ka tātai aunoa i ngā hua ka tauhohenga pāhekoheko.
  6. Ka whakaawhiwhia te hua o te tatauranga.

Me pehea te tatau i te rōrahi o te pūtoru

Ko te Cuboid he pouaka totoka ko ia mata he tapawha o te horahanga kotahi, he waahi rereke ranei.
Ka whai te roa, te whanui me te teitei o te tapatoru.

Rōrahi o te pūtoru = (roa × whānui × teitei) wae pūtoru.

Tātai Rōrahi Tapawhā

Rōrahi = roa × whanui × teitei

Tauira tatau

Kimihia te rōrahi o te pūtoru o te rahi 14 cm × 12 cm × 8 cm.

14 × 12 × 8 henemita pūtoru.
= 1344 cm pūtoru.
Nō reira, te rōrahi o te pūtoru = 1344 cm pūtoru.

Ki te hiahia tatou ki te huri i nga waeine o te rōrahi ki ngā waeine rerekē, ka taea e tatou te huri i ngā waeine o te rahi ki te ōrite o te rōrahi i te tuatahi,
hei tauira,
he 12.5 inihi te rahi o te mataono, 14 inihi me te 9.3 inihi.
He aha te rōrahi i roto i te ft³?

12.5 in = 12.5 ÷ 12 ft = 1.042 ft
14 in = 14 ÷ 12 ft = 1.167 ft
9.3 in = 9.3 ÷ 12 ft = 0.775 ft
1.042 × 1.167 × 0.775 in = 0.94241085 ft³
i muri i te whakaawhiwhi, he 0.94 i roto i te ft³ te rōrahi

Porowhita me te Mataono

Apūtoruhe mea ahua pouaka. E ono ona mata papatahi, he koki tika nga koki katoa. A ko ona mata katoa he tapawha. He parama hoki na te mea he rite tonu te whitinga o te roa. Inaa, he tapawha tapawha.

Ina rite nga roa e toru ka kiia ko aporaka(hexahedron ranei) a he tapawha ia mata. He tapatapahi tonu te mataono, he mataono ano hoki.
