A 16 by 48 pool holds how many gallons of water?

The volume of a rectangular prism (in this case, a swimming pool) is equal to the length times the width times the height.

So, for a 16 by 48 pool that is 5 feet deep, the volume is:

```

V = 16 ft x 48 ft x 5 ft = 3,840 cubic feet

```

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

```

V = 3,840 cubic feet x 7.48 gallons/cubic foot = 28,761.6 gallons

```

Therefore, a 16 by 48 pool holds approximately 28,762 gallons of water.
