To calculate the volume of the aluminum foil, you can use the formula:
\[ \text{Volume} = \frac{\text{Mass}}{\text{Density}} \]
Given:
- Mass = 19.8 grams
- Density = 2.75 grams per cubic centimeter
Substituting in the values:
\[ \text{Volume} = \frac{19.8 \text{ grams}}{2.75 \text{ grams/cm}^3} \]
Calculating the volume:
\[ \text{Volume} = 7.2 \text{ cm}^3 \]
Therefore, the volume of the aluminum foil is:
\[ \boxed{7.20} \text{ cm}^3 \]
