Query: Interior Volume of Banados-Teitelboim-Zanelli Black Hole   We calculate the interior volume for the three-dimensional
Banados-Teitelboim-Zanelli black hole in this paper. To that end, we obtain the
volume functional and numerically find a path to extremize it, before choosing
a spacelike hypersurface to get an asymptotic analytical expression for the
interior volume based on the characteristics of the path.
