1. Find the specific heat of aluminum
The specific heat of aluminum is given in
\frac {cal}{g\,C}
Therefore, if you multiply the specific heat by the number of grams and the number of degrees Celsius that you wish to raise the temperature, the result will be in calories. You can convert that to whatever units are expected in the final answer.
