volume calculation

Dear all,
I need a way to find the volume of a multidimensional shape in the  
coordinates (x1,x2,x3,...,xn), that comes from an inequality like  
D(x1,x2,x3,...,xn) < L (with 3 variables i get a nice weird shape in  
R^3, with more i don't plot it)
In other words I let Mathematica calculate where in the space of the  
solutions the inequality is solved and i'd like to have the numerical  
"volume of the solutions".
What strategy should i use? The function D is not invertible...
Thank you,
Filippo
