The value is 1.7320
The calculating of square roots by hand was taught in primary school before portable calculators existed. I had forgotten the method , but found the site listed below which shows the procedure that we used well over 50 years ago.

The next site shows several other methods of hand calculation. There is one similar to the one noted above.
On this site go down to section 4 for that similar example.
