Answer :
That is a question about density.
To solve that question, it is important to know how we can obtain the Density of an object. Below, you can see the formula:
[tex]\boxed{D=\frac{m}{v} }[/tex]
[tex]D = Density\\m = Mass\\V = Volume[/tex]
Now, it is easy to answer, right? We just replace the values in the formula. The mass is 87.329g and the volume is 32.32cm³. So,
[tex]D=\frac{m}{v} \\\\D = \frac{87.329g}{32.32cm^3} \\\\D \approx 2.70g/cm^3[/tex]
Therefore, the density of the the aluminium is approximately 2.7 g/cm³.
I hope I've helped. ^^
