If 2 x 10^16 cm-3 boron atoms are added to silicon as a substitutional impurity and are distributed uniformly throughout the semiconductor, determine the distance between boron atoms in terms of the silicon lattice constant. (assume the boron atoms are distributed in a rectangular or cubic array.)

import math

x=int(input("enter a number: "))

print (math.sqrt(math.fabs(
