To calculate the density of the cube, you need both mass and volume. The formula for density is:
\[
\text{Density} = \frac{\text{Mass}}{\text{Volume}}
\]
Given that you have the mass of the cube as 72.9 g, but you did not provide the volume of the cube, I cannot directly calculate the density. However, you mentioned density values: 8.1 g/cm³, 2.7 g/cm³, and 0.37 g/cm³.
Next, let’s determine what the substance could be based on the given densities:
1. **Sugar** typically has a density around 0.85 g/cm³, so it does not match any of the given options.
2. **Iron** has a density of about 7.87 g/cm³, which is close to 8.1 g/cm³.
3. **Aluminum** has a density of about 2.7 g/cm³.
Given these densities, if the density you are calculating is closest to 8.1 g/cm³, then the substance is likely **Iron**.
If you can provide the volume of the cube, I can give you an exact density calculation.
\[
\text{Density} = \frac{\text{Mass}}{\text{Volume}}
