superr confused can you please show all work along with the answer Thank you

Answer 1

google "face centered cubic cell"

the length of the diagonal of a face of the cube is two atom diameters

the cube edge length is √2 times the atom diameter

the volume is the edge length cubed (^3)

Answer 2

So I would square root 197 and put it to the power or three?
