Questions & Step-by-Step Solutions

A river is flowing at a rate of 1000 liters per second. How many cubic meters of water does it flow in one hour?
  • Step 1: Understand that 1 cubic meter is equal to 1000 liters.
  • Step 2: Identify the flow rate of the river, which is 1000 liters per second.
  • Step 3: Calculate how many seconds are in one hour. There are 60 seconds in a minute and 60 minutes in an hour, so 60 x 60 = 3600 seconds in one hour.
  • Step 4: Multiply the flow rate (1000 liters/second) by the total seconds in one hour (3600 seconds).
  • Step 5: Perform the multiplication: 1000 liters/second × 3600 seconds = 3600000 liters in one hour.
  • Step 6: Convert liters to cubic meters by dividing the total liters by 1000 (since 1 cubic meter = 1000 liters). So, 3600000 liters ÷ 1000 = 3600 cubic meters.
  • Unit Conversion – Understanding the conversion between liters and cubic meters, where 1 cubic meter equals 1000 liters.
  • Flow Rate Calculation – Calculating the total volume of water over a period of time using flow rate.
