Anyị kwesịrị ịgbakọ ibu nke a 4×8 akwandina nke aluminum efere na a ọkpụrụkpụ nke 1/8 inch.
Mbụ, anyị kwesịrị ịma njupụta nke aluminom na otú ọkpụrụkpụ ya si emetụta olu ya.
Mmekọrịta dị n'etiti uka (m) na olu (V) Enwere ike igosipụta nke ihe site na usoro mgbakọ na mwepụ ndị a:
m = ρ × V
ebe ρ (ro) bụ njupụta nke ihe, nke na-akọwa oke ọnụ ọgụgụ nke ihe ahụ.
Njupụta nke aluminom bụ ihe dịka 2.7g/cm^3.
Na 1 inch = 2.54 cm, so 1/8 inch = 0.3175 cm.
Enwere ike gbakọọ olu nke efere aluminom site na usoro a:
V = ogologo × obosara × ọkpụrụkpụ = 4cm × 8cm × 0.3175cm
Dochie olu a na njupụta nke aluminom n'ime usoro uka, anyị nwere ike nweta ibu nke aluminom efere.
