Which of two bars of the same mass – copper or aluminum – has a larger volume.

The volume of a bar can be found by the formula V = m / p, where V is the volume, m is the mass, p is the density. Based on this formula, we can say that the volume of that body will be larger, with less density. You can find out the density of copper and aluminum from a special table: for copper, the density is 8.92 g / cm ^ 3, for aluminum – 2.7 g / cm ^ 3 (the density is taken at room temperature). Since 2.7 <8.92, it follows that the volume will be greater for aluminum.
