SUMMARY
The discussion focuses on calculating the volume of cork required to keep 20% of a 40 kg child above water using cork floats with a density of 0.28 g/cm³. Applying Archimedes' principle, the buoyant force must equal the weight of the submerged portion of the child. The necessary volume of cork can be determined by calculating the weight of the child that needs to be supported and the corresponding volume of cork needed to achieve this buoyancy.
PREREQUISITES
- Understanding of Archimedes' principle
- Basic knowledge of density and volume calculations
- Familiarity with buoyancy concepts
- Ability to perform unit conversions (grams to kilograms, cm³ to m³)
NEXT STEPS
- Calculate the buoyant force required to support a 40 kg child using Archimedes' principle
