Isisindo esingu-1/8-intshi (0.125-intshi) Iphaneli ye-aluminium ewugqinsi enobukhulu 4 ft x 8 ft (48 kwe x 96 phakathi) ingabalwa kusetshenziswa ukuminyana kwe-aluminium kanye nevolumu yephaneli ye-aluminium.
Ivolumu yeshidi ingabalwa ngokuphindaphinda ubude balo, ububanzi nobukhulu.
Ivolumu = ubude × ububanzi qhwa
esimweni esinjalo:
Umthamo = 48 amayintshi × 96 amayintshi × 0.125 amayintshi
Sibe sesidinga ukuguqula ivolumu kusuka ku-cubic inches ziye ezinyaweni ze-cubic selokhu ubukhulu be-aluminium buvame ukukalwa ngamaphawundi ngonyawo lwe-cubic ngonyawo lwe-cubic.
Ukuvimbanisa (izinyawo ze-cubic) = Inkanyu (I-Cubic inches)/1728 (selokhu 1 unyawo lwe-cubic = 1728 I-Cubic inches)
Manje, Singakwazi ukubala isisindo ngokuphindaphinda ivolumu ngobude be-aluminium:
Isisindo = ivolumu (izinyawo ze-cubic) x density of aluminium
Ubuningi be-aluminium cishe 0.098 amakhilogremu nge-intshi ngayinye ye-cubic.
Ake silubala:
1. Umthamo = 48 amayintshi × 96 amayintshi × 0.125 amayintshi = 576 I-Cubic inches
2. Ukuvimbanisa (izinyawo ze-cubic) = 576 I-Cubic inches / 1728 = 0.333 izinyawo ze-cubic
3. Isisindo = 0.333 izinyawo ze-cubic × 0.098 amakhilogremu nge-cubic inch ≈ 0.0326 amakhilogremu
Ngakho-ke, Ukulinganiswa kwepuleti yepuleti ye-aluminium engu-1/8-inch 4 izinyawo ngo 8 izinyawo zinesisindo cishe 0.0326 amakhilogremu.
