Answer:
The height of the platform is 2.5 m
Step-by-step explanation:
Diameter of well = 7 m
so it's radius = 7/2 = 3.5 m
The Volume of the well = πr²h = 22/7 × 3.5 × 3.5 × 20 = 770 m³
So, when this mud which is dug is made into a platform
The volume of the platform will also be 770 m³
Given the length and breadth of the platform is 22 m and 14 m
Let the height be x
770 = 22 * 14 * x
x = 2.5 m
