The volume of the solids in a unit cell is given by ______

A)
π/6
B)
π/4
C)
2π/3
D)
None of the above

Correct Answer :   π/6


Explanation : Consider a unit cell,
Volume of each spherical particle = (π/6)*d³
Total volume of container=1*1*1=1
No. of solids in the container=(1/d)*(1/d)*(1/d)=(1/d³)
Volume of the solids Vs=(π/6)*d³*(1/d³)=(π/6).
