Answer 1

p atom =corner =8
contribution of each corner=1/8
p=8*1/8=1
Q=face centre =6
c4 axis passes through two opp. face centre
q=6-2=4
contribution of face centre =1/2
q=4*1/2=2
so formula =pq2

Answer 2

p atom =corner =8

contribution of each corner=1/8

p=8*1/8=1

Q=face centre =6

c4 axis passes through two opp. face centre

q=6-2=4

contribution of face centre =1/2

q=4*1/2=2

so formula =pq2
