Using GroupBy, Count and Sum in LINQ Lambda Expressions

Question

I have a collection of boxes with the properties weight, volume and owner.

I want to use LINQ to get a summarized list (by owner) of the box information

e.g.

Answer 1

        var q = from b in listOfBoxes
                group b by b.Owner into g
                select new
                           {
                               Owner = g.Key,
                               Boxes = g.Count(),
                               TotalWeight = g.Sum(item => item.Weight),
                               TotalVolume = g.Sum(item => item.Volume)
                           };
