A parallel-plate capacitor has an equivalent capacitance of 850 pF.?

A parallel-plate capacitor has an equivalent capacitance of 850 pF. The area of each plate is 6 cm*2 and the thickness of the dielectric is 0.02 cm. If the material used as the dielectric has a constant of 8, how many sections are there in parallel? -Thank you in advance :)
