To solve the problem step-by-step, we will follow these calculations: ### Step 1: Determine the number of atoms in one unit cell of BCC In a body-centered cubic (BCC) structure, there are: - 8 corner atoms, each contributing \( \frac{1}{8} \) of an atom to the unit cell. - 1 atom at the body center. Calculating the total contribution: ...
