#### Explanation:

The **density** of a substance tells you the mass of exactly *one unit of volume* of said substance.

In your case, aluminium is said to have a density of

#"density Al" = color(blue)("2.70 g") color(white)(.)color(darkorange)("cm"^(-3))#

This tells you that **every**

All you have to do now is use the density of aluminium as a **conversion factor** to go from *cubic centimenters* of aluminium to *grams*

#10.0 color(red)(cancel(color(black)("cm"^3))) * color(blue)("2.70 g")/(color(darkorange)(1)color(red)(cancel(color(darkorange)("cm"^3)))) = color(darkgreen)(ul(color(black)("27.0 g")))#

The answer is rounded to three **sig figs**.
