internal arrangement of atoms
Halite forms in a cubic manner. This is because the arrangement of the atoms Na and Cl form a cubic lattice.

They differ in the number of atoms within the unit cell. Body-centered contains two atoms, face centered contains four. Images online or in textbooks show this best.
The shape of a mineral depends on the chemical structure that the bonds form between atoms in the mineral. A cubic mineral (such as pyrite) has a chemical structure that, as bonds are made, a cubic shape is formed.

Copper has a higher density then silver. So a cubic inch of copper weighs more then a cubic inch of silver.

One cubic centimeter of silver weights 10.497g so 2.5 cubic centimeters of silver would be 26.2425g.
The arrangement of atoms or ions in a crystal.
internal arrangement of atoms
Uncharged molecules and atoms are packed more efficiently in closed-packet structures. Hence theses uncharged molecules and atoms do not crystallize in simple cubic structures.
The number of mercury atoms is 11,74458.10e23.

1000 grams of silver with a density of 10,49 has a volume of 95,33 cubic centimeters (a cube 4,47 centimeters on a side).
According to Wikipedia:"A diamond is a transparent crystal of tetrahedrally-bonded carbon atoms in a covalent network lattice that crystallizes into the diamond lattice which is a variation of the face centered cubic structure."
A face-centered cubic unit cell is a cube. All sides are the same length and all face perpendicular to each other, with an atom at each corner and an atom in the middle of each face of the cell.
