The Space Lattice and Unit Cells

Every matter consists of atoms, molecules, and ions. If these atoms, molecules, and ions (micro-particles) are represented in a three-dimensional space-occupying certain specific points in space, then these arrangements are termed as space lattices and the specific points which are being occupied by atoms, molecules and ions are termed as lattice points. The atoms, molecules, and ions at the lattice points are generally grouped in a regular fashion and repeat periodically at the three-dimensional space.

Question

When examining the atomic layers used to construct the models (i.e., select the HCP and FCC bodies to be visible at the same
time), which appears to be packed more densely?
Comparison of FCC and HCP
Is the HCP model stacked the layers in an A-B-A-B-... or an A-B-C-A-B-C-... stacking sequence? (In other words, were atoms in
the first and third layers aligned or not?)
When you examine the tilted FCC model, is the added third layer of close-packed spheres aligned with those in the first layer,
or with the voids of the first layer? In other words, is FCC an A-B-A-B-... or an A-B-C-A-B-C-... stacking sequence?
When looking at large numbers of atoms (i.e., many unit cells stacked together), and considering that atoms don't care about
orientation with respect to "horizontal" and "vertical," explain the similarities and the differences between the FCC and HCP
structure.
