Final answer:
To convert the volume of fresh water on Earth from cubic kilometers to cubic meters, you multiply by 1 x 10⁹, resulting in 3.73 x 10¹⁷ m³. To convert to liters, you multiply the volume in cubic meters by 1,000, yielding 3.73 x 10¹⁺ liters.
Step-by-step explanation:
The total amount of fresh water on Earth is estimated to be 3.73 x 10⁸ km³. To convert this volume into cubic meters, recall that 1 km³ equals 1 x 10⁹ m³. So, the volume in cubic meters is calculated by multiplying 3.73 x 10⁸ km³ by 1 x 10⁹ m³/km³, which gives us 3.73 x 10¹⁷ m³.
To convert the volume into liters, we use the fact that 1 cubic meter equals 1,000 liters. Thus, multiplying the volume in cubic meters by 1,000 gives the volume in liters, which is 3.73 x 10¹⁷ m³ x 1,000 L/m³ = 3.73 x 10¹⁺ L of fresh water on Earth.
Calculation for cubic meters:
- Identify the conversion factor: 1 km³ = 1 x 10⁹ m³.
- Multiply the given volume by the conversion factor: 3.73 x 10⁸ km³ x 1 x 10⁹ m³/km³ = 3.73 x 10¹⁷ m³.
Calculation for liters:
- Identify the conversion factor: 1 m³ = 1,000 L.
- Multiply the volume in cubic meters by the conversion factor to get liters: 3.73 x 10¹⁷ m³ x 1,000 L/m³ = 3.73 x 10¹⁺ L.
