Measuring Lengths Using Body Parts and Everyday Techniques

This video tutorial explains how to measure the length of objects using body parts such as the hand, foot, and forearm. It introduces the concept of length as a dimensional distance and describes various traditional measurement units like hand span, cubit, foot span, and pace. The tutorial provides practical examples of measuring objects like tables, classrooms, and strings of flowers using these methods.

What is the primary concept introduced for measuring lengths in this chapter?

• Using a ruler

• Using body parts

• Using a laser

• Using a measuring tape

Which body part is used to define a 'cubit'?

• The distance between the thumb and little finger

• The distance between the elbow and the middle finger

• The distance between the big toe and the ankle

• The distance covered in a single step

What is a 'foot span'?

• The distance between the thumb and little finger

• The distance between the elbow and the middle finger

• The distance covered in a single step

• The distance between the big toe and the ankle

How is a 'pace' defined in terms of body-based measurement?

• The distance between the big toe and the ankle

• The distance covered in a single step

• The distance between the thumb and little finger

• The distance between the elbow and the middle finger

Why is hand span used to measure smaller lengths?

• Because it is easier to use

• Because it is a traditional method

• Because smaller lengths can be measured easily by using hand span

• Because it is more accurate

Which measurement method is demonstrated for measuring the length of a classroom?

• Pace

• Cubit

• Foot span

• Hand span
