The density of iron is 7.9 *10.3 kg/m3, and the volume of iron is v 12*80.
m =ρv =7.9* 10^3* 12*80
For example:
The specific gravity of steel is 7.86t/m3 = 7.86kg/dm3 = 7.86g/cm3.
Iron plate weight = iron plate volume times iron plate density.
The density of iron plate is 7.86 grams per cubic centimeter.
1 1* 100*6* 100* 1.2*7.86/ 1000=6225. 12
So the weight of the iron plate is about 6225. 12kg.
Extended data:
Pure iron is a metallic crystal with silvery white metallic luster, usually gray to gray-black amorphous fine particles or powder, with high-purity iron wire color.
It has good ductility, electrical conductivity and thermal conductivity.
It has strong ferromagnetism and belongs to magnetic materials.
Density: 7.874 g/cm3
Specific heat capacity: 460 Joule/(kg℃).
The speed of sound propagation in iron: 5120m/s.
Pure iron is soft, but if it is an alloy of iron and other metals or iron doped with impurities, the melting point will usually decrease and the hardness will increase.
Crystal structure: face-centered cube and body-centered cube.
The relative atomic mass of iron is 55.85, and the electronic configuration formula of ground state atom is: 1s2? 2s2？ 2p6？ 3s2？ 3p6？ 3d64s2 .？ [3] (Valence electron in bold)
