Practical Demonstration of Calculating the Volume of Rectangular wood in BS7 Science

In this video I demonstrated how to calculate the Volume of rectangular wood in Basic 7 Science, using ruler.

Using the rectangular wood having all the 3 dimensional spaces=LBH

With the help of the ruler, calculation was practically simple for BS 7 to understand.

This is what I intend to do, more especially in this lockdown due to the covid-19 pandemic to help our students in Basic Schools.

Enjoy the lesson
