Here is the problem: The density of aluminum is 2.70 g/cm3. What is the volume of a 16 g block of aluminum. Please show your steps...I want to figure this out!

Your question seems to be one of specific gravity, rather that volume. Specific gravity of aluminum is a constant and compared to the same volume of the weight of a drop of water of the same sample of aluminum will answer your question.
Density or volume of weight is relative to the Mohs' scale of specific gravity. In other words, if you dipped a sample of your aluminum into an equal specific gravity liquid, it would be invisible and would be suspended in the liquid. It would not float, nor would it sink. In your case, you would have to know the exact specific gravity liquid that upholds this fact. Many of these liquids are not available to the public, but to only gemologists; of which I am one.
The steps I would take to determine the mineral or material you have would be to test it in specific gravity liquids from the least to the most. You can create a harder specific gravity as an example by adding salt to a boiling egg. The more salt you add, the more the egg will float to the surface, since the saturation of salt increases the specific gravity of the water and makes the egg lighter than the weight of the water.
Remember, specific gravity equals an equal volume of water in mass as the test subject. For instance the specific gravity of Sapphires and Rubies are 4.0. That means that the family of Corundum minerals weigh four times their weight as the same volume of water.
Additionally, heavy battle ships float because they displace more weight than the water that they displace. People wonder how a multi-ton ship can float. If the ship weighs 600,000 tons, then it if displaces 600,100 tons of water; it will float.

Divide the mass by the density... so that would be 16g / (2.70g/cm3) = 5.9259259259259259259259259259259 cm3 which rounds to...
5.93 cm3
Good luck!

x * 2.70 g/cm3 = 16 g ' divide both sides by 2.70 g/cm3
x = 16/2.70 cm3
x = 5.926 cm3

volume = mass / density
v = 16 / 2.7 = 5.93 cubic centimeters
