Answer:
Lets 1st find the volume of the mud dug out. Formula used will be \piπ r²h.
Hence we have volume = 22/7 × (7/2)² × 20
We also have the volume of the cuboid at L x B x H
Here L = 22 and B = 14, we need to find H
Since the two volumes are equal, we have
22 x 14 x H = 22/7 × (7/2)² × 20
Hence we get the Height of the platform as 2.5m
