~In the simple cubic lattice each part of atoms touch other part of atoms on the middle of the edge's length.

~This lattice includes 1 atom because there is 1 part of atom in each corner so :1 divided by 8 times 8 is equal to 1

~The simple cubic lattice is a cube with an part of atom in each corner
