Volume of prism is 1/3 volume of pyramid.
Introduction
This activity is the way of find out the volume of pyramid and prism in a single.In this activity the volume of pyramid is 1/3 of volume prism which can be seen on the screen on the applet.The three parts of pyramid are rotating around 90° anticlockwise.This shows a volume of pyramid is 1/3 of volume of prism.
Objective;
Student will be able to find the volume of pyramid is and 1/3 of prism ,
User guideline ,
Click the slide button and observe the figure carefully.

Construction protocol
1) Open Geogebra 3D Graphics window .
2)Take a cube from input bar or using tool from 3D graphics,
3)Take a pmd1 =Pyramid(A,B,C,D,F) from Input bar then colour it
4)Take a line AB by using line tool ,
5) Take input bar then text Rotate(pmd1,α ,AB)Then click on create slider Rotate line AB for slider (0-90°)
6)Take a pmd2 =Pyramid(D,E,G,H,F) then colour it,
7) Take input bar the text Rotate(pmd2,α ,GH) .
8) Similarly Take another one Pyramid 3 then colour it ,
9) Then show or hide object or level line ,Axes ,Greed and Plane for good visualization.
10) Finally rotate it then watch the visualization of cube and pyramid.
