Here it goes,
It is given that,
Diameter of well is 3.5m
Radius of well is 3.5/2 = 1.75m
Height of well is 12m
The volume will be,
22/7*r*r*h
=22/7*1.75*1.75*12
=115.5 m cube
We now need to consider
volume of well = volume of platform
115.5
Both of their volume will be equal as it is spread evenly.
Hope it helps
