Scientific paper

The entropy for a black hole in a de Sitter space is approached within the
framework of spacetime foam. A simple model, made by $N$ wormholes in a
semiclassical approximation, is taken under examination to compute the entropy
for such a case. An extension to the extreme case when the black hole and
cosmological horizons are equal is discussed.
