Using a calculator one will get 10.583.
One could estimate this though:
sqrt(63) is going to be just slightly under 8 [sqrt(64)]. Let's call it 7.9
sqrt(7) is going to be under 3 [sqrt(9)], but moreso than what sqrt(63) was to sqrt(64) Let's call it 2.6 maybe 2.7.
7.9 + 2.6 = 10.5
7.9 + 2.7 = 10.6
So it's between 10.5 and 10.6 ... not a bad estimate right?
I hope this helped.
