If you know the density of aluminum, you can determine the volume of a specific mass of aluminum. Aluminum has a density of 2.70g/cm3.
Density = mass/volume. If we know any two variables, we can manipulate the density equation to find the third variable. In this case, we know mass and density, so to find the volume, do the following calculation:
Volume = mass/density
Volume Al = (27g Al)/(2.70g/cm3 Al) = 10cm3 Al. So, 27g of Al has a volume of 10cm3. *
* This answer should technically have two significant figures. As written, it only has one, because trailing zeroes without a decimal are not significant. We can indicate two significant figures by writing it in scientific notation as 1.0 x 101cm3, or we can write it with a decimal as 10. cm3.

27.3 g is the mass of an aluminum sample with a volume of 10.0 cm3.
What is g + (-5) = 27
The foil has a volume of 45 cm x 30 cm x 0.0010 cm = 1.35 cm3. Density is mass per unit volume, so with a density of 2.7g/cm3, 1 cm3 of aluminum will weigh 2.7g. Therefore 1.35 cm3 will weigh 2.7 x 1.35 = 3.645g
The density of copper is 10.0 g/mL. What is the volume in milliliters of a 2184-g ingot of copper?
Cube root the volume as for example if its volume was 27 then the cube root of 27 is 3 which is its side length
