You'd need a lot more than that for coverage. These balloons are not stationary. They are constantly traveling around the Earth. At the very least, need the balloons around the circumference of the earth. Also, I doubt that the coverage is a perfect square. I'd think the coverage footprint would be more circular, and so you'd need overlap in order to get coverage.
