Denote K as the value of the number of neighboring cells in a cellular network that cannot use the same frequencies for transmission. The figure below shows the cases

Consider an area of 100 square miles over which a cellular network is laid out. We know that if there are 100 total cells in the area and K=4, the overall cellular network capacity in the area is C. Now, if we increase the cell numbers in this area to 700 and make K=7, the capacity of the cellular network will be= ______ C.
