A scale model is a smaller version of an object that accurately represents its proportions and details. These models are often used in various fields, such as architecture, engineering, and hobbies. For example, a model airplane might be built at a 1:48 scale, meaning it is 48 times smaller than the actual aircraft. This allows people to study and visualize the design without needing the full-sized version. Scale models can also be found in train sets or dioramas, where they help create realistic scenes. They are popular among collectors and enthusiasts who enjoy building and displaying these miniature representations of their favorite objects, like cars or buildings.
