Number of atoms in a simple cubic unit call and Body Centred cubic unit cell

The video tutorial explains the structure and atom distribution in cubic unit cells, focusing on simple and body-centered cubic unit cells. It describes how atoms are positioned and shared among unit cells, calculating the total number of atoms in each type of unit cell. The simple cubic unit cell has atoms at each corner, contributing 1/8 of an atom per unit cell, resulting in one atom per unit cell. The body-centered cubic unit cell has additional atoms at the center, leading to a total of two atoms per unit cell.

Explain how corner atoms are shared in a simple cubic unit cell.

What is the total number of atoms in a body-centered cubic unit cell?
