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

1.	Predict the percentage of space filled by particles in bcc
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.
