Bekenstein and Hawking derived the expression for black hole entropy as, $$ S_{BH}={c^3 A\over 4 G \hbar}. $$ We know from the hindsight that entropy has statistical interpretation. It is a measure of possible number of microstates that is consistent with a particular macrostate. My question is how far string theory predict this result.
