Question

the order of packing observed in cubic close packing
​

Answer 1

Answer:

In this kind of close packing in solids, the spheres of the third layer are exactly aligned with those of the first layer. Thus, if we name the first layer as 'A' and second as 'B', then the third layer can again be named as 'A'.
