If the height of a cuboid is increased by 2 cm, it becomes a cube, and the surface area is increased by 56 square cm. What is the volume of the original cuboid You have to write the formula. Don't write it blindly

It is known that the length = width of the cuboid increases by 2
So the increased surface area = 2 * length * height + 2 * width * height
2 * length * 2 + 2 * length * 2 = 56
4 * length + 4 * length = 56
Length = 7
So: width = 7, original height = length - 2 = 5
Cuboid volume = length * width * height = 7 * 7 * 5 = 245 CC
