A cuboid is 8cm in length, 6cm in width and 5cm in height. Saw it into two identical cuboids. What is the maximum increase in surface area 5cm high

There are three situations:
1. 8 × 6 × 2 = 96 square centimeter
2. 8 × 5 × 2 = 80 square centimeter
3. 6 × 5 × 2 = 60 square centimeter
So the maximum increase is 96 square centimeters
