⇒ Length = 15 × 14/15 = 14 cm
⇒ Breadth = 12 × 13/12 = 13 cm
⇒ Height = 11 cm
⇒ The total area of the four side faces after change in length and breadth = 2 × 11(14 + 13)
⇒ The total area of the four side faces after change in length and breadth = 594 cm‌2
⇒ Change in total area = 594 – 594 = 0
∴ No change in the total area of the four side faces.
