Am I being dense?

” but more especially the bulk density of Bennu is only 1.26+/-0.07 g/cc. So as there are a lot of voids between the boulders, their density will be close to 1.0 g/cc on average.”

I’m confused.  You appear to say that the bulk density (1.26) is greater than the boulder density (average 1.0).  How can this be?  Is the latter figure a typo for 2.0, say?
