Let the length of the edges of the two cubes be ‘a’ cm and ‘b’ cm, respectively According to the question, 6a2 + 6b2 = 1572 Or, a2 + b2 = 1572/6 = 262 And, ab = 99 Using the formula, x2 + y2 = (x – y)2 + 2xy 262 = (a – b)2 + 2 × 99 Or, (a – b)2 = 262 – 198 Or, (a – b)2 = 64 Or, a – b = ±8 So desired difference = 8 cm
