Sidinga ukubala isisindo sika-a 4×8 isixwexwe ye-aluminium plate enogqinsi lwe 1/8 intshi.
-Yinhloko, sidinga ukwazi ukuminyana kwe-aluminium nokuthi ukushuba kwayo kuthinta kanjani umthamo wayo.
Ubudlelwano phakathi kwenqwaba (m) kanye nevolumu (V) yento ingavezwa ngale fomula yezibalo elandelayo:
m = × × V
lapho ρ (rho) ukuminyana kwento, echaza ubukhulu beyunithi ngayinye yevolumu yento.
Ukuminyana kwe-aluminium cishe ku-2.7g/cm^3.
Futhi 1 inch = 2.54 cm, ngakho 1/8 inch = 0.3175 cm.
Ivolumu yepuleti ye-aluminium ingabalwa ngefomula elandelayo:
V = ubude × ububanzi × ukujiya = 4cm × 8cm × 0.3175cm
Ukushintsha le volumu kanye nokuminyana kwe-aluminium kufomula yobuningi, singathola isisindo sepuleti le-aluminium.
Umphumela wokubala uthi: isisindo se-aluminium plate 35.28 amagremu.
Ngakho-ke, A 4×8 ishidi le-aluminium plate enogqinsi lwe 1/8 intshi inesisindo 35.28 amagremu.
4×8 I-aluminium sheet iyona esetshenziswa kakhulu. Uma ufuna ukuthenga futhi wazi 4×8 ishidi le 1/8 intshi intengo aluminium, Ngizokunikeza ikhotheshini enemininingwane.
