Indeed, we are looking for the upper limit. The ball be completely covered with dimples that touch one another (but never overlap). The problem states that there are overlaps with 100 hemispherical dimples (of diameter 0.15cm). As we want to avoid the overlaps, I assume the number of dimples...

The approximate number of dimples is 1/(1-√(1-r^2/R^2))
