Export the product dimensions (length, width, height) ?

Is it possible to export the product dimensions (length, width, height) to the Google product feed?  Currently it only exports the weight.  I am using version for 4.20

You can do it
Open the file google.xml in the folder FeedSchema
and add such columns

  <FeedAttribute>
    <Id>1001</Id>
    <FeedCaption>length</FeedCaption>
    <FeedName>length</FeedName>
    <FieldNameCode>length</FieldNameCode>
    <Required>false</Required>
    <IgnoreNullOrEmpty>false</IgnoreNullOrEmpty>
    <ActionId>0</ActionId>
  </FeedAttribute>
  <FeedAttribute>
    <Id>1002</Id>
    <FeedCaption>width</FeedCaption>
    <FeedName>width</FeedName>
    <FieldNameCode>width</FieldNameCode>
    <Required>false</Required>
    <IgnoreNullOrEmpty>false</IgnoreNullOrEmpty>
    <ActionId>0</ActionId>
  </FeedAttribute>
  <FeedAttribute>
    <Id>1003</Id>
    <FeedCaption>height</FeedCaption>
    <FeedName>height</FeedName>
    <FieldNameCode>height</FieldNameCode>
    <Required>false</Required>
    <IgnoreNullOrEmpty>false</IgnoreNullOrEmpty>
    <ActionId>0</ActionId>
  </FeedAttribute>
