<human>:  John is an eccentric millionaire. He decides to fill his swimming pool with bottled water. A cubic foot of water is 25 liters. His pool is 10 feet deep and 6 feet by 20 feet. A liter of water costs $3. How much does it cost to fill the pool?
<bot>: How many cubic feet is the pool? ** The pool is 10*6*20=<<10*6*20=1200>>1200 cubic feet
How many liters is the pool? ** That means it is 25*1200=<<25*1200=30000>>30000 liters
How much does it cost to fill the pool? ** So it cost 3*30,000=$<<3*30000=90000>>90,000
#### 90000
