An aluminum block has a mass of 82.0 g and a volume of 12.8 cm3. what is the block's density to the nearest g/cm3? a.5.2 g/cm3 b.5.9 g/cm3 c.6.4 g/cm3 d.7.0 g/cm3

Density is mass over volume. If you put it into a formula it would look like this:



Based on the problem given, you can see that the mass of the aluminum block is 82.0 g and the volume is 12.8 cm3. Just put that into your equation and solve for it:



The answer is then letter C.

D)can be increased in a closed system
