The volume of a piece of granite is 6 dm3. Calculated what kind of pushing force will act on it when it is fully immersed in kerosene.

To determine the buoyancy (or Archimedean) force, you need to know the following formula:
F = g * ρl * Vt (F-Archimedean force; g-acceleration of gravity (9.8 N / kg); ρl-density of the liquid, in this case kerosene (800 kg / m3); Vt-body volume (6 dm3 = 0.6 m3).
F = 9.8 * 800 * 0.6 = 4704 H
Answer: F = 4704 N
