1. Calculate the volume in cubic feet:
* Length x Width x Depth = Volume
* 54 ft x 36 ft x 6 ft = 11,664 cubic feet
2. Convert cubic feet to gallons:
* There are approximately 7.48 gallons in one cubic foot.
* 11,664 cubic feet x 7.48 gallons/cubic foot = 87,353.92 gallons
Therefore, your pond holds approximately 87,353.92 gallons of water.
