Formula of the weight of the aluminum plate : aluminum plate is 72.8 mm length、38.0 mm width、 3.0mm thickness , and inquiry the weight of this aluminum plate.
The density of aluminum : 2.702g/cm3.
The density of aluminum plate : pure aluminum plate density of 2.71g/cm3 , alloy aluminum plate density of 2.68 g/cm3.
The quality of the aluminum plate = thickness of aluminum plate length * width * density .
A length of 72.8 mm , 38.0 mm wide , thickness of 3.0 mm aluminum plate volume :
V=72.8 * 38.0 * 38.0 (mm) = 8299.20 mm3 = 8.29920 (cm3)
The quality of aluminum plate : 8.29920*2.71g=22.4908g=0.0225kg
