Question

how can be heights can be calculated between girls and boys​

Answer 1

There's no proven way to predict a child's adult height. However, several formulas can provide a reasonable guess for child growth. Here's a popular example:

Add the mother's height and the father's height in either inches or centimeters.

Add 5 inches (13 centimeters) for boys or subtract 5 inches (13 centimeters) for girls.

Divide by two.

Answer 2

• Mark some points in a corner wall of a room better using metre scale or centimetre scale .
• Then measure your height by standing close to the wall and place a thin scale over your head to have an accurate reading.
