A board that is 20.0 cm wide, 5.00 cm thick, and 3.00 m long has a density 300 kg/m³. The board is floating partially submerged in water. What fraction of the volume of the board is above the surface of the water?

Question

Quizplus · Accepted Answer

The fraction of the volume of the board above the water is determined by the ratio of the board's density to the density of water. Since the board's density is 300 kg/m³ and water's density is 1000 kg/m³, the fraction submerged is 0.300, so the fraction above water is 1 - 0.300 = 0.700.
