When and how many minutes are multiplied by ten, a day is 1400 minutes, 1400 times 10 times 3. Only in this way can we work out how many milliliters of water 1 person wasted in 1 day, multiply it by a * * * number of people multiplied by 365 days a year, and finally divide it by the rate of 1000. Divide the result by the ratio of 1000. Multiply the calculated cubic meters of water by 2. (Calculate the litres of water wasted in 24 hours in 1 question. Just do the following problem, 1mL= 1000 liters = 1000 cubic meters.
