Actually Welcome to the Concept of the Surface areas and Volume.
Since Box A is cube, it's volume is Side^3
hence taking the cube root of 512 , we get as,
Side length of Box A is 8 m.
hence diving 8/2 = 4 m
4 m is a side of Box B.
hence, Volume of Box B is = (4)^3 = 64 cubic metres.
Vol. Box B = 64 m^3
