A. I alone sufficient while II alone not sufficient to answer B. II alone sufficient while I alone not sufficient to answer C. Either I or II alone sufficient to answer D. Both I and II are not sufficient to answer
Explanation: Allow a metre between each edge. Then,a2 = 64 a = 8 m a2 = 64 a2 = 64 a2 = 64 a2 = 64 a Volume = 512 m3 (8 x 8 x 8 m3).As a result, I am the only one who can provide an answer.a = 8 m a = 8 m a = 8 m a = 8 Volume = 512 m3 (8 x 8 x 8 m3).As a result, II alone provides the answer.
