1. Calculate the volume in cubic feet:
* Volume = Length x Width x Depth
* Volume = 2 ft x 3 ft x 3 ft
* Volume = 18 cubic feet
2. Convert cubic feet to gallons:
* There are approximately 7.48 gallons in 1 cubic foot.
* Gallons needed = Volume in cubic feet x 7.48 gallons/cubic foot
* Gallons needed = 18 cubic feet x 7.48 gallons/cubic foot
* Gallons needed ≈ 134.64 gallons
Therefore, you would need approximately 134.64 gallons to fill the pond.
