Answer:
[tex]4 cm^{3}[/tex]
Explanation:
As you can see density of aluminium is 2.7 g/cm3 so in order to calculate the volume of a piece of aluminium that is 10.8 g we just ahve to clear the volume from the density formula:
[tex]Density=\frac{mass}{volume} \\Volume=\frac{mass}{density}[/tex]
Now that we have cleared the formula we just have to insert the values:
[tex]Volume=\frac{mass}{density}\\Volume= \frac{10.8}{2.7}\\ Volume= 4 cm^{3}[/tex]
So the volume of the aluminum piece is 4 cm3 so the volume of water displaced would be the same, 4 cm3.
