A scale model is a representation of an object with the same shape as the real object. Models
can be larger or smaller than the actual object but are
often smaller

Architects often make scale models of the buildings or
structures they plan to build. Models can give them an
idea of how the structure will look when finished. Each
measurement of the building is scaled up or down by
the same factor
Bob is building a scale model of his bike. He wants
his model to be as long as his bike.
11. If Bob's bike is 60 inches long, how long will his model be?
12. THINK SMARTER If one wheel on Bob's model is 4 inches across, how
many inches across is the actual wheel on his bike? Explain.
