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

245
One side of a cuboid is a square,
So if the edge of a cube is a, then the height is A-2,
The surface area of cube is 6a × a
The surface area of the cuboid is 2A * a + 4a (A-2)
Cube surface area - cuboid surface area = 56
6A×A—2A*A+4A(A-2)＝56
A=7
The height should be 5
The volume is 7 × 7 × 5 = 245

If the length of a rectangle remains unchanged and the width is increased by 4 meters, it will become a square. The area is 56 square meters larger than the original. What is the area of the original rectangle

56 / 4 = 14-4 = 10 14x10 = 140, the original area is 140 square meters
