It's very useful to know the volume of material in the Earth's crust and mantle, but before we move on it's also worthwhile to note that the Earth's crust and mantle have several Biblical synonyms.
The Volume of Earth’s Mantle
Hell is a Destination for Souls
We (that's me and the Holy spirit) have made an extensive study of how the zones of the interior of the Earth, or levels of hell, may be deduced from Biblical Hebrew and Greek.
Above and Below
A recurring theme in scripture is heaven above and Earth below. Orientation occurs for the first time on the second day. It's an ordering of the universe which occurred in response to the creation of gravity.

After Noah's flood the region in the interior of the Earth, formerly occupied by the great deep (tehom), is now a great gulf or mega chasm of open space that Jesus spoke of in Luke 16:26 (sheol).
Bars, Beams and Pillars
Four different Biblical phrases refer to a feature of the internal structure of the Earth. They confirm our hypothesis that the interior of the Earth was tehom before Noah's flood, and sheol after it.
The Great Gulf
Based on seismological data and the Matty's Paradigm spherical hollow Earth model (SHEM) we can definitively say that Abraham and Lazarus are in a chamber in the lower mantle. The rich man is in the molten core of the Earth.
