A copper cube measuring 1.57cm on edge and an aluminum cube measuring 1.66cm on edge are both heated to 57.1oC and submerged in 100.0mL of water at 21.8oC. What is the final temperature of the water when equilibrium is reached? (Assume a density of 0.998 (g/mL) for water.) Im am really lost with how to even start this problem, please explain solution as much as possible.
