You can parametrise it as follows:
http://en.wikipedia.org/wiki/Ellipsoid

Then perform a triple integration to find the volume in spherical coordinates. But the problem I got with this method is finding the limits of integration for p.

Thank you very much Defennnder

but I dont understand it .

What exactly don't you understand? Are you familiar with using triple integrals in order to find the volume of some three-dimensional region?

If you have no idea how to find a volume of rotation, why are you attempting a problem like this?

Does the method of volume by rotation work if all three semi-axes are unequal?

it must be equal

Do you mean to say all are equal? Or 2 are equal? Because if all are equal, then you have a sphere. If only 2 are equal then you only need to find the volume by rotation by integration as Halls said.
