Determine the photon flux, Physics

Suppose that the x rays are emitted from a focal spot isotropically. The photon flux is 3.28 x 106 photons mm-2 sec-1 at a distance of 0.75 m from the focal spot. What is the photon flux at a distance of 10 cm from the focal spot? Neglect the effects of air attenuation.
