We calculate the energy and hydrostatic pressure densities of a hot quark-gluon plasma in thermal equilibrium through diagrammatic analyses of the statistical average {l_angle}{Theta}{sub {mu}{nu}}{r_angle} of the energy-momentum-tensor operator {Theta}{sub {mu}{nu}}. To leading order at high temperature, the energy density of the long wavelength modes is consistently extracted by applying the hard-thermal-loop resummation scheme to the operator-inserted no-leg thermal amplitudes {l_angle}{Theta}{sub {mu}{nu}}{r_angle}. We find that, for the long wavelength gluons, the energy density, being positive, is tremendously enhanced as compared to the noninteracting case, while, for the quarks, no noticeable deviation from the noninteracting case is found. {copyright} {ital 1996 The American Physical Society.}
