You are assuming a spherical particle. There is no assumption of shape in the above paragraph. If a silver atom is .2nm then if the atoms were stacked end to end, making a rod, it would be 5 atoms long for a 1 nanometer particles. A sphere would contain 31 as you say. A shape other than a rod or sphere would fall in the range of 5 to 31 atoms, so the statement above is not really far off.
