title: Triple Integration with Python / Numpy / Scipy
body: <p>I am new to python and learning by following Python "Scientific lecture notes
  Release 2013.1" tutorial.
  Please help me solve this triple intergration problem in the srcreenshot below (Pg 70). I have covered the previous content of that tutorial.
  Please provide step-wise commands with explanation if possible because being an Aerospace engineer programming concepts are new to me.</p>
  
  <p>Thank You.</p>
