Formula of packing fraction

WebAug 28, 2024 · The “packing fraction” in a hexagonal close packed cell is 74.05%; that is 74.05% of the total volume is occupied. The packing fraction or density is derived by assuming that each atom is a hard sphere in contact with its nearest neighbors. WebDec 3, 2024 · But you can estimate the number of circles that will fit by knowing that the limiting density of the triangular packing is π 2 3.
