A CUBE of Aluminum is removed from a kiln (that's an industrial oven) at a temperature of 350°C. The
Aluminum cube is placed in a beaker containing 200. mL of water. The temperature of the water is
15.0°C before the Aluminum cube is placed in it. After a few minutes, the temperature of the water
stabilizes at 97.1°C. Determine the DIMENSIONS of the Aluminum cube. The density of aluminum is
2.70g/cm?
