Mathematics

This is a related rates problem where you connect how one quantity changes to how another changes. The key insight is to write the volume formula $V = s^3$, then differentiate both sides with respect to time to relate $\frac{dV}{dt}$ (what you want) to $\frac{ds}{dt}$ (what you're given). Once you have that relationship, substitute the specific edge length to find the answer.
