Explanation:
Density is defined as the mass of a substance present in per unit volume.
Mathematically, Density = [tex]\frac{mass}{volume}[/tex]
As toothpick, pencil and log are all made up of same wood. So, this means that there will be same composition as amount of mass present in per unit volume will be the same.
Therefore, we can conclude that toothpick, pencil and log all of them will have same density.
