### How much water is in Estanque de la Luz?

Daniel took 89 steps for the width and 96 steps for the length. His stride is 2.5 ft/step. The depth of Estanque de la Luz is 3.7 meters according to the sign there.

```Width: 89 steps * 2.5 ft/step = 225.5 ft
Length: 96 steps * 2.5 ft/step = 240 ft
Depth: 3.7 meters * 0.3048 feet/meter = 12.1 ft
Volume: 225.5 ft * 240 ft * 12.1 ft = 654852 ft3
Volume in gallons: 654852 ft3 * 7.48 gallons/ft3 = 4898293 gallons
```

Therefore, the Estanque de la Luz holds about 4,900,000 gallons of water. Thank you for the assignment, if you have any changes to the lenght or width values please post them here.

#### At 200 GPM out and 0 GPM in, how long would Estanque de la Luz take to go dry?

At approximately 4,900,000 gallons of water stored and only the one canal of 200 GPM outflow:

```Minutes held = 4,900,000 gal / 200 GPM = 24500 min
Hours held = 24500 min / 60 min/hr = 408.333 hrs
Days held = 408.333 hrs / 24 hr/day = 17.01 days
```

Therefore there are about 17 days of storage in Estanque de la Luz.
