Question

you provided with 3 cubes one of iron the other one zinc and third one aluminium each of volume 1cm3 on weighing cubes it was found the iron cube weighed 7.6g zinc weighed 4.2 g and aluminium weighed 2.7g which of these cubes is dense explain
​

Answer 1

Iron is denser than zinc and than aluminium

Density depends on mass and volume.If the mass is more than density will be more and if the volume is more than density will be less

In this case the volume is fixed for the three elements i.e, 1 cc and now mass comes into play..the mass of iron is the greatest so iron will have the maximum density in this scenario..
