Lesson 8.6 Measure in Inches and Feet

Essential Question Why is measuring in feet different from measuring in inches?

As you can see, one foot is much longer than one inch. We, therefore, use feet to measure bigger objects, such as the height of a door or the length of a car. We can also use feet to measure the distance between things.
When two people stand apart, it would take a lot of inches to measure the distance between them.
