A cubic-kilometre lake has about 400,000 times the volume of a 50 m swimming pool. Selected basis: an example for 50 m swimming pool; an example for A cubic-kilometre lake; approximate values.
Too small to see at this scale. The ring marks its true-scale position, not its volume. The shape has not been enlarged.

A 50 m swimming pool is a large pool built for competitive swimming events, including international competitions.
Example: 50 × 25 m and uniformly 2 m deep. 2.5 million litres; actual competition-pool depth and volume vary.
