Question

If the density of iron is 7.8 g/cm3 and you find an iron nail weighing 15g, what would the volume of the nail be?

Answer 1

Density =mass/ volume   ⇒ volume=mass/ density

Data:
density=7.8 g/cm³
mass=15 g

volume=15 g/7.8 g/cm³=1.92 cm³

answer., the volume of the nail will be 1.92 cm³

Answer 2

117 cm3 is the answer
