  • 1 answers

  • Packing faction or Packing efficiency is the percentage of total space filled by the particles.

  • Both  hcp & ccp though different in form are equally efficient. They occupy the maximum possible space which is about 74% of the available volume. Hence they are called closest packing.

  • Packing Efficiency ={tex} \frac{Volume\ occupied\ by\ all\ the\ spheres\ in \ unit\ cell}{Total\ volume\ of\ the\ unit\ cell}\times 100{/tex}
