SUMMARY
The surface atom density of an fcc(111) surface can be calculated using geometric principles and the quadratic formula. The fcc(111) surface is triangular, with all angles measuring 60 degrees. By determining the height of the triangle and the area it encloses, one can accurately compute the number of atoms per unit area. This method builds on the calculations previously established for fcc(100) and fcc(110) surfaces.
