A cubic piece of platinum metal (specific heat capacity = 0.1256 J/°C g) at 200.0°C is dropped into 1.00 L of deuterium oxide ('heavy water,' specific heat capacity = 4.211 J/°C g) at 25.5°C. The final temperature of the platinum and deuterium oxide mixture is 29.1°C. The density of platinum is 21.45 g/ cm³ and the density of deuterium oxide is 1.11 g/mL. What is the edge length of the cube of platinum, in centimeters?
