To find the difference in height, we can calculate the distance from the top of the platform to the point of depth in the water.
The height of the platform is 10 meters, and the depth in the water is 6 meters.
To find the difference in height, we subtract the depth reached in the water from the height of the platform:
10 meters (height of the platform) - 6 meters (depth in the water) = 4 meters.
So the difference in height is 4 meters.
