In order to determine the packing density for the body-centered cubic crystalline structure, the spatial diagonal \(e\) of the cube-shaped unit cell is considered. The three atoms lying on this diagonal are just touching each other. Thus, the spatial diagonal corresponds to 4 times the atomic radius \(r\). farma egypt
