Answer:
2,500,000 litres or 2.5 megalitres of water.
Olympic size pools measure: 50 metres long, 25 metres wide, and a minimum of 2 metres deep.
______________________________________
Length x width x depth x 7.5 = volume (in gallons)
Multiplying that by the depth gives the volume in cubic meters. If you'd like to find the pool volume in gallons, multiply your results by 7.5, as there are 7.5 gallons for each cubic foot.
