Which is lighter than steel or aluminum?

In order to find out the answer to this question, let us compare the mass of steel and aluminum.
The formula for mass in terms of volume and density looks like this: m = ρ × V. Suppose that, according to the condition, the same volume of aluminum and steel is taken. In this case, the only thing that can affect the mass of metals is their density. The density of steel is 7800 kg / m3, and that of aluminum is 2700 kg / m3. That is, as you can see, the density of aluminum is much lower. The correct answer would sound like this: for the same volume, aluminum is lighter than steel.
