Question

Consider a cube containing n unit cells of a cubic system. A plane ABCD obtained by joining the mid point of the edges on one of its identical faces had atoms arranged as shown. Let p be the packing fraction. Choose the correct option :

  1. n=1comma p equals fraction numerator 22 over denominator 21 square root of 2 end fraction    
  2. n=8,p equals fraction numerator 11 over denominator 21 end fraction    
  3. n=8,p equals fraction numerator 11 over denominator 14 end fraction    
  4. n=1,p equals fraction numerator 11 square root of 3 over denominator 28 end fraction    

The correct answer is: n=8,p equals fraction numerator 11 over denominator 21 end fraction
