<p>Assume we can decompose a set $A$ in $\mathbb{R^n}$ of Hausdorff-dimension n into sets $(A_t)$ $t\in [0,1]$ of Hausdorff-dimension n-1 whose n-1-dimensional volume is known (for example is zero). </p> <p>Are there any possibilities beside the coarea-formula that allow us to say something about the measure of A?</p>
