Answer :
To find the depth of the swimming pool, use the formula for the volume of a rectangular solid and substitute the given values to calculate the depth as 2.5 meters.
The depth of the Olympic-size swimming pool can be calculated using its volume, length, and width.
First, use the formula for the volume of a rectangular solid:
Volume = Length x Width x Depth
4000 = 80 x 20 x Depth
Depth = 4000 / (80 x 20) = 2.5 meters
Depth = 2.5 meters
