- What does a scale model's ratio compare?
Show the answer
The model's linear dimension to the prototype's. Scale is the ratio of a linear dimension on the model to the same dimension on the real object, called the prototype.
- In a 1:8 scale model, one unit represents how many units on the real object?
Show the answer
Eight. A 1:8 scale means one length unit on the model equals eight of the same units on the prototype.
