All have same density.
Density = Mass/Volume
Mass = Volume x Density
They are made of the same material (copper from the same sheet), the density of the material is constant. If you increase the volume by a number of times, the mass will also increase by the same number of times.
From this question, since the mass is the same, we can infer that the 3 objects have the samw volume

Unless they build the shape like ships where the enclosed volume contains air and other less dense materials
Yup, but that would be the overall density.
