Answer:
The edge length or side of the cube be 'a', and the radius of each particle be 'r'.
a=2r
Volume of cube =a3
(2r)3=8r3
In simple cube, each unit cell has only one sphere,
Volume of sphere = 4 /3πr3
Packing efficiency × Volume if a sphere /Volume of the cube ×100%
= (4/3 πr3) /8r3 ×100=52.4%.
