 Hello and welcome to the session. Today I will help you with the following question. The question says water is pouring into a cuboidal reservoir at the rate of 60 liters per minute. If the volume of reservoir is 108 meter cube, find the number of hours it will take to fill the reservoir. Volume of cuboid is equal to L multiplied by B multiplied by H where L is the length of cuboid, B is the breadth of cuboid and H is the height of cuboid. And we also know that 1 meter cube is equal to 1000 liters. This is the key idea for this question. Now let's see the solution. It is given in the question that water is pouring into a cuboidal reservoir at the rate of 60 liters per minute. Thus we have in 1 minute 60 liters of water is pouring. So in 60 minutes, 60 multiplied by 60 that is equal to 3600 liters of water will pour. We know that 60 minutes is equal to 1 hour. So we say that in 1 hour 3600 liters of water will pour. Volume of reservoir given to us is equal to 108 meter cube and we know that 1 meter cube is equal to 1000 liters. Therefore, volume of reservoir is equal to 108 multiplied by 1000 liters which is equal to 108 triple zero liters. Thus we have 3600 liters of water will be filled in 1 hour as we are supposed to find the number of hours it will take to fill the reservoir. For this we will find the number of hours for 108 triple zero liters of water to be filled. Thus we have 108 triple zero liters of water will be filled in 108 triple zero upon 3600 hours. These two zeros gets cancelled with these two zeros and 36 30 times is 1080 so we have this is equal to 30 hours. We say 30 hours time will be taken to fill the tank. Hence our final answer is 30 hours. So hope you enjoyed the session. Have a good day.
