The world's largest pumped hydroelectric facility in Bath County, Virginia, has a total energy storage capacity of about $30 \mathrm { GWh } _ { \mathrm { e } }$. Assuming the same conversion efficiency for a compressed air storage facility (which is optimistic), calculate the dimensions of a cubic chamber that, at a pressure of $5.0 \mathrm { MPa }$, has the same energy storage capacity as the Bath County station.
