The phrase "Cloud 9" is a metaphorical expression that refers to a state of euphoria or extreme happiness. The origin of the phrase is unclear, but it is believed to have originated from the idea of being on the highest, most blissful cloud in the sky. The number 9 is often used in idiomatic expressions to signify the highest or best possible state, which is why the phrase "Cloud 9" was chosen to convey the idea of reaching the pinnacle of happiness. Therefore, it is called Cloud 9 and not Cloud 8, 9 or 10 because it represents the ultimate feeling of joy and contentment. **

The weight of a cube is directly proportional to the volume of the cube. Since the volume of a cube is proportional to the cube of its edge length, if a cube with an edge length of 20 cm weighs 8 kg, then a cube with an edge length of 10 cm would weigh 1 kg. This is because the volume of the smaller cube is 1/8th of the volume of the larger cube, so its weight would also be 1/8th of the weight of the larger cube. **
