Predict the percentage of space filled by particles in fcc – InterviewSolution

1.	Predict the percentage of space filled by particles in fcc
Answer» Solution :The cubic close packed (CPP)is also called FACE central cubic(fcc) lattice. In both of these packings `74%` space is filled The REMAINING space is present in the form of TWO TYPESOF voids-octahedral voids and tetrahedral voids.Other type of packing of particles. While in body- centred cubic lattice (bcc)`68%` space is filled, in simple cubic lattice only `52.4%` space is filled.
