Request At what % body fat would a person naturally float? (Additional info below)

A little challenge for you guys and something I was wondering about before:

Let's assume that every change in fat % has an equal % opposite change in muscle mass, the non-fat+ non-muscle % will be 30% and for the sake of simplicity, let's assume it is all water.

Assume a person laying flat in/on the water. Assume either 12L of air inside the body or 0, whichever works for you.

The person doesn't have anything in their digestive system. Make any further assumption that you need.
