Pool Volume Calculator: How Many Gallons Does Your Pool Hold?

```

Volume = Length * Width * Height

```

In this case, the length is 12 feet, the width is 36 feet, and the height is 6 feet. So, the volume of the pool is:

```

Volume = 12 * 36 * 6 = 2592 cubic feet

```

Since there are 7.48 gallons in 1 cubic foot, the number of gallons of water in the pool is:

```

Gallons = Cubic feet * 7.48

```

```

Gallons = 2592 * 7.48 = 19388.16 gallons

```

Therefore, there are approximately 19,388 gallons of water in a 12x36 pool that is 6 feet deep.
