The density of states for an extended MIT bag model is studied numerically by using a parameterized smooth representation which provides the best fit to the numerical data. It is found that the mass dependence of the surface term in the density of states agrees with that derived from multi-reflection theory calculation. The mass dependence of the curvature term in the density of states is extracted for finite values of the quark mass. The scaling properties of the data, assumed in the parameterization, are studied. The difference between the parameterized smooth representation determined by a best fit and the results derived from direct smoothing of the numerical data are discussed. The fluctuations in the density of states are also discussed. We provide a smooth representation of the density of states of a spherical cavity for non-relativistic particles.
