If the height of a cuboid increases by 2 cm, it will become a cube, and the surface area will increase by 56 square cm. What is the volume of the cuboid?

What is the perimeter of the base of the cuboid
56 △ 2 = 28 (CM)
What is the length and width of a cuboid
28 △ 4 = 7 (CM)
What is the height of a cuboid
7-2 = 5 (CM)
The original cuboid volume is
7 × 7 × 5 = 245 (cm3)
