3a. What is the Bravais lattice of the black lattice points AND how many black lattice points are in the unit cell? 3b. Considering your answer to part \( 3 \mathrm{a} \), how many interstitial sites are in the unit cell that have the same coordination number as the pink polyhedron? \( \underline{W} \) here are those that are not shown located? 3c. Considering your answer to part \( 3 a \), how many interstitial sites are in the unit cell that have the same coordination number as the blue polyhedron? Where are those that are not shown located?
