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