Challenge Problems
Push your limits with challenges.
Question 1
A solid cube of wood displaces 40 cm³ of water while weighing 30 N. Given that the density of water is 1 g/cm³, will it float or sink? Show your calculations.
💡 Hint: Check the relationship between weight and displaced water.
Question 2
A ship is designed with an overall mass of 100,000 kg and a volume of 1,000 m³. Calculate its density and determine if it will float in freshwater (density of water = 1,000 kg/m³).
💡 Hint: Remember density comparison for buoyancy.
