The length, breadth and height of a cuboid is 15 cm, 12 cm and 11 cm respectively. Length is reduced by `6 2/3%` and breadth is increased by `8 1/3%` while the height remains the same. What is the change in the total area of four side faces of the cuboid ? ( considering the rectangle formed by the length and breadth as base)
