1. **State the problem:** We need to find the density of an object given its mass and volume. 2. **Formula:** Density ($\rho$) is calculated by the formula: $$\rho = \frac{\text{mass}}{\text{volume}}$$ 3. **Given values:** - Mass = 168 grams - Volume = 24 cubic centimeters 4. **Calculate density:** $$\rho = \frac{168}{24}$$ 5. **Simplify:** $$\rho = 7$$ 6. **Interpretation:** The density of the object is 7 grams per cubic centimeter. **Final answer:** 7 (Option A)
