How do you create a bounding box around a part

Hi,

I am currently using Solidworks 2012. My question is how do you create a bounding box in X,Y and Z axis. I will be using these dimensions for material cost estimates. I have seen some companies use bounding boxes to estimate 3D printing parts useing other softwares but i need to be able to use Solidworks to create these sizes for me. Any suggetions would help. I included a file also of a test part similar to what I will be needing a bounding box around.

Thanks

Matt
