  The equilibrium and nonequilibrium properties of an Ising ferromagnetic cubic
shell have been extensively studied by Monte Carlo simulation using Metropolis
single spin flip algorithm. Although geometrically the Euclidean dimension of
the cubical shell is three, interestingly, the Ising ferromagnetic cubic shell
undergoes ferromagnetic phase transition at a temperature which is very close
to that for two-dimensional Ising ferromagnet. Surprisingly, the Ising
ferromagnetic cubic shell shows a strange (neither exponential nor stretched
exponential) kind of relaxation behaviour, instead of exponential relaxation as
usually observed in the two dimensional Ising ferromagnet. The metastable
lifetime of a ferromagnetic Ising cubical shell is studied as a function of the
applied magnetic field. Here also, the cubic shell behaves more likely a
two-dimensional object as found from statistical analysis and comparison with
Becker-D\"oring prediction of classical nucleation theory.
