You can't build an ordinary 3-sphere in 3D Euclidean space; a 3-sphere is a hypersphere. Are you considering 4D spacetime as the container of the 3-sphere, or did you just mean the volume of the 2-sphere in 3-space (as opposed to its shell area)?
Sorry, I meant to say 3-ball bounded by a 2-sphere in Euclidean space. The edit window of my GP post is still open so I've fixed it.
