1. The problem involves understanding the unit cm³, which stands for cubic centimeters, a measure of volume. 2. When dealing with repeated measurements, the range is the difference between the maximum and minimum values in the data set. 3. To find the uncertainty using the range, identify the largest and smallest measurements. 4. Calculate the range as $$\text{Range} = \text{Maximum value} - \text{Minimum value}$$. 5. The uncertainty can be estimated as half the range: $$\text{Uncertainty} = \frac{\text{Range}}{2}$$. 6. This method helps quantify the variability in repeated measurements, giving a sense of precision. 7. For example, if measurements are 10 cm³, 12 cm³, and 11 cm³, then the range is $$12 - 10 = 2$$ cm³ and the uncertainty is $$\frac{2}{2} = 1$$ cm³. 8. This means the volume measurement is approximately $$11 \pm 1$$ cm³, where 11 is the average of the measurements. This approach is useful for estimating uncertainty when multiple measurements are available.
