The density of water is approximately 1 g/cm3
. An ice block with a height of 2 cm, length of 2 cm, width of 5 cm, and mass of 18.4 g is dropped in water. Will it float or sink? In 3–5 sentences, show your calculations and explain how you arrived at your conclusion.(4 points)

Volume = 2 cm × 2 cm × 5 cm = 20 cm³.
Density of the ice block = mass/volume = 18.4 g / 20 cm³ = 0.92 g/cm³, which is less than water (1.00 g/cm³), so it will float.
It will displace 18.4 g (18.4 cm³) of water when floating, so the submerged fraction = 18.4/20 = 0.92 (92%), leaving 8% above the surface.
Conclusion: the block floats because its density is lower than water.
