U = (sqrt(s)/n)*(BH./B+2.*H).^2/3;
I am not sure why it is not taking sqrt. Is it a problem with the 's' data, or how i wrote the formula?

Rather than fiddling around with strings (e.g. using STR2NUM) the best solution by far would be to import your numeric data properly. If you upload your data file by clicking the paperclip button then someone can show you how.

You should transform char format to double then do your work
B = str2num(B);
H = str2num(H);
n = str2num(n);
s = str2num(s);
U = (sqrt(s)./n).*(B.*H./B+2*H).^2/3;
