Calculate the porosity of a formation composed of uniform spherical grains of radius r in a cubic packing arrangement, when the central space is occupied by the largest possible sized spherical particle. Such a particle could not squeeze inside the cell between the other particles, but must have been placed there during initial rock deposition
