## Introduction to Height

Height is a way to measure someone or something from base to top or head to toe. In other words, height tells how tall someone or something is. Height is measured in distance units, i.e., meters, centimeters, millimeters, etc.

We can compare how tall we become as we grow up. We often compare the average height of men and women of different countries.

Look at the four walls of your room. The distance from the floor to the roof is the **height** of the wall. Recall how, in the school assembly, your class is arranged with the shortest child in the front and the tallest child at the end of the line. It is done so that everyone can see the stage. Therefore, tall and short are **terms** we use to indicate height in relative terms. Relative terms mean when we compare one with the other.

In math, height can be defined as vertical distance from the top to the base of the object.

Here, the **height** of the rectangular prism and triangle have been marked.

## Fun Facts!

- Height is measured along the vertical axis on a graph.
- Height from the sea level is referred to as altitude.

## Origin of the Term: Height
