Ping dove off a 10 meter platform he reached a depth of 6 meters in the water. What was the change in height?

The change in height can be calculated by subtracting the depth reached in the water from the height of the platform.

Change in height = Height of platform - Depth reached in water
Change in height = 10 meters - 6 meters
Change in height = 4 meters

Therefore, the change in height is 4 meters.

To find the change in height, we need to subtract the final depth from the initial height.

Given:
Initial height (platform) = 10 meters
Final depth (underwater) = 6 meters

The change in height can be calculated as:
Change in height = Initial height - Final depth

Substituting the given values:
Change in height = 10 meters - 6 meters

Therefore, the change in height is 4 meters.
