What is a unit bar in the context of model drawing?

• A type of graph paper

• A box representing a value in a problem

• A tool for measuring length

• A bar for drawing straight lines

Why is it important to draw unit bars of equal size?

• To make the drawing look neat

• To ensure the values represented are equal

• To use less paper

• To confuse the solver
