Solid State: JEE Main 2021 Chemistry question

A certain element crystallises in a bcc lattice of unit cell edge length 27$\mathop A\limits^o$. If the same element under the same conditions crystallises in the fcc lattice, the edge length of the unit cel in $\mathop A\limits^o$ will be ____________. (Round off to the Nearest Integer). [Assume each lattice point has a single atom] [Assume $\sqrt 3$ = 1.73, $\sqrt 2$ = 1.41]
