Start learning 50% faster. Sign in nowLet the length of the edges of the two cubes be ‘a’ cm and ‘b’ cm, respectively According to the question, 6a2 + 6b2 = 1326 Or, a2 + b2 = 1326/6 = 221 And, ab = 98 Using the formula, x2 + y2 = (x – y)2 + 2xy 221 = (a – b)2 + 2 × 98 Or, (a – b)2 = 221 – 196 Or, (a – b)2 = 25 Or, a – b = ±5 So desired difference = 5 cm
