Abstract The free energy and entropy of a general spherically symmetry black hole are calculated by quantum statistic method with brick wall model. Two different kinds of approximation are used to calculate the number of states in transverse spatial space. The final results are approximately equal except a rational numerical constant. The formulas of free energy and entropy, evaluated by each one of the two different kinds of approximation, are the same except some numerical constants. The free energy and entropy are dependent on the spacetime dimensions D. When D = 4, they reduce to the usual well known results.
