We use the brick-wall method to investigate thermodynamical quantities around a static Gibbons-Maeda dilaton black hole and show that each of these quantities contains an additional spin-dependent term and that the usual result that the entropy density, energy density, and pressure take the same forms as in flat spacetime holds only for the leading term. Our results are compatible with the early conclusions that the black hole entropy is not exactly proportional to the horizon area and that Hawking radiation is not purely thermal.
