My question is: 10 boxes each contain 50 bottles of water. Each bottle has a capacity of 12 liters and is filled up to 3/4 of its capacity. How many liters of water altogether are contained within the bottles in the boxes? Your thoughts:
Since each water bottle has a capacity of 12 liters, when filled up to 3 / 4 of capacity, each carries 3 / 4 * 12 = 9 liters of water. If there are 50 bottles of water in each box, the number of liters the water bottles in a box are carrying is 50 * 9 = 450 liters. In 10 boxes containing bottled water, the total number of liters in the water bottles is 450 * 10 = 4500 liters. The final answer: 4500.
