Ubunzima be-1/8-intshi (0.125-intshi) Iphaneli ye-aluminium ye-aluminium enemilinganiselo 4 ft x 8 ft (48 kwi-X 96 ngaphakathi) Ingabalwa kusetyenziswa uxinzelelo lwe-aluminium kunye nevolumu yephaneli ye-aluminium.
Umthamo wephepha unokubala ngokuphindaphindiweyo, Ububanzi kunye nobungqingqwa.
Umthamo = ubude × ubude
kule meko:
Umthamo = 48 i-intshi × 96 i-intshi × 0.125 intshi
Emva koko, kufuneka siguqule ivolumu ukusuka kwi-cuic i-cubic kwiinyawo ze-cubic oko ukuxinana kwe-aluminium kuhlala kulinganiswa kwiiphulucture unyawo.
Ivolumu (Iinyawo ze-cubic) = Ivolumu (i-intshi i-cubic)/1728 (ukusukela 1 unyawo lwe-cubic = 1728 i-intshi i-cubic)
Ngoku, Singabala ubunzima ngokuphinda ivolumu ngokuxinana kwe-aluminium:
Ubunzima = ivolumu (Iinyawo ze-cubic) x Ukuxinana kwe-aluminium
Ukuxinana kwe-aluminium kuya malunga 0.098 Iipawundi kwi-intshi nge-intshi.
Masibale:
1. Umthamo = 48 i-intshi × 96 i-intshi × 0.125 intshi = 576 i-intshi i-cubic
2. Ivolumu (Iinyawo ze-cubic) = 576 i-intshi i-cubic / 1728 = 0.333 Iinyawo ze-cubic
3. Ubunzima = 0.333 iinyawo zeicuba × 0.098 Iipawundi kwi-intshi nganye ye-cubic ≈ 0.0326 Iipawundi
Ngoko ke, I-1/8-intshi-i-aluminick iplati 4 iinyawo nge 8 Iinyawo zinobunzima 0.0326 Iipawundi.
