Calculate the density of a block of aluminum that has a volume of 15cm^3 and a mass of 40.5g

The formula for density is:

density = mass / volume

Substituting the values given:

density = 40.5g / 15cm^3

Simplifying:

density = 2.7 g/cm^3

Therefore, the density of the block of aluminum is 2.7 g/cm^3.
