Evidence from the paper

The volume (V0), the bulk modulus (B0), and its pressure derivative (B0') at ambient pressure were estimated by a least-square fit of calculated V-E curves to the integrated form of the third-order Birch-Murnaghan's equation of state. Table I: MgO | a = 4.259 Å | B0 = 160 GPa | B' = 4.01 | (a) This work.

Additional notes

lattice constant a
4.259 Å
note
Only the cubic lattice constant a is tabulated, not V0; Table II (this work) also gives aggregate B = 164 GPa from elastic constants at zero pressure.
