Animesh147:
it's wrong, u have taken lateral surface area while the question demands total surface area which is 6a square.
bro surface area cube is 6a square not 4a square that is it lateral surface area
that is what am saying that u have written wrong in answer above.
but if we take 6a^2 the answer doesn't come appropriate
bro i don't give answer of this question
