Best Answer

This might be best determined by experiment. While natural rubber is slightly denser than water and will sink, there will be some small amount of air trapped in a rubber band ball, reducing the density to some extent. Attempting to model and calculate the air content seems somewhat impractical without experimental data, and if you are going to experiment anyway, why not just find the answer directly?
