title: Using GroupBy, Count and Sum in LINQ Lambda Expressions
body: <p>I have a collection of boxes with the properties weight, volume and owner.</p>
  
  <p>I want to use LINQ to get a summarized list (by owner) of the box information</p>
  
  <p>e.g.</p>
  
  <pre><code>**Owner, Boxes, Total Weight, Total Volume**  
  Jim,     5,     1430.00,      3.65  
  George,  2,     37.50,        1.22
  </code></pre>
  
  <p>Can someone show me how to do this with Lambda expressions?</p>
