Because their bodies are not fully grown
The weight of a person is influenced by various factors such as body composition, muscle mass, and overall health in addition to height. Without additional information, it is not possible to determine the weight of a person solely based on their height. An individual's weight can vary significantly depending on these factors.
their is no average weight, it is determined by your height
