1. **State the problem:** Lilia wants to hang string lights along the top edge of her wall, which is 8 feet long. We need to find out how many centimeters of string lights she needs. 2. **Formula and conversion rule:** To convert feet to centimeters, use the conversion factor: $$1 \text{ foot} = 30.48 \text{ centimeters}$$ 3. **Calculate the length in centimeters:** $$8 \text{ feet} \times 30.48 \frac{\text{cm}}{\text{foot}} = 243.84 \text{ cm}$$ 4. **Interpretation:** Lilia needs 243.84 centimeters of string lights to cover the 8-foot length of her wall. **Final answer:** $$\boxed{243.84 \text{ centimeters}}$$
