1. The problem asks to convert $9\ \text{mm}^3$ to cubic centimeters (cm³). 2. Recall the conversion between millimeters and centimeters: $1\ \text{cm} = 10\ \text{mm}$. 3. Since we are dealing with volumes, we cube the conversion factor: $$1\ \text{cm}^3 = (10\ \text{mm})^3 = 10^3\ \text{mm}^3 = 1000\ \text{mm}^3$$ 4. To convert $9\ \text{mm}^3$ to cm³, divide by 1000: $$9\ \text{mm}^3 = \frac{9}{1000}\ \text{cm}^3 = 0.009\ \text{cm}^3$$ 5. Therefore, $9\ \text{mm}^3$ equals $0.009\ \text{cm}^3$.
