Volumetric relationship between various shapes

We use containers of different shapes and sizes to measure ,transfer as well as store things. Amount of quantity stored depends on the shape as well. 

We will consider 3 shapes Sphere, Cylinder and Cone . These are hollow shapes so that we can measure volume. Radius and height of all the containers are equal. 3D printing these containers gives us control over the dimensions.

With one common parameter these 3D shapes are printed and activity conducted to understand the relationship.

Here is the explainer video.
