SUMMARY

The density of a solid object floating in water can be calculated using the principle of buoyancy. In this case, the object has 54% of its volume submerged, indicating that its density is less than that of water, which has a density of 1 g/cm³. To find the object's density, apply the formula for density (mass/volume) and consider the relationship between the submerged volume and the density of water. The density of the object is determined to be approximately 0.74 g/cm³.

PREREQUISITES
  • Understanding of basic physics concepts, particularly buoyancy.
  • Familiarity with the formula for density (mass/volume).
  • Knowledge of the density of water (1 g/cm³).
  • Ability to manipulate percentages in relation to volume.
NEXT STEPS
  • Study Archimedes' principle for a deeper understanding of buoyancy.
  • Learn how to calculate density using mass and volume measurements.
  • Explore the concept of specific gravity and its applications.
  • Investigate the effects of temperature on the density of liquids.
USEFUL FOR

Students in physics or engineering courses, educators teaching buoyancy principles, and anyone interested in understanding the physical properties of floating objects.

Homework Statement


A solid object floats with 54% of its volume beneath the surface of the water. What is the object’s density? Give answer in g/cm3.


Homework Equations


Density = mass/ volume


The Attempt at a Solution



I know that the density must be more than one, because the object is floating somewhat, but I don't know how to calculate what the density is, exactly. If anyone has a better formula for this problem, I'd much appreciate it.
 
Physics news on Phys.org
Hint: what is the density of water? And what does it mean when something is floating on water?
 
If the density of water is one, and its floating, than it must be less than one?

How do I figure out exactly what it is, though? I don't have the mass or the exact density or the volume, so my formula is useless...
