Answer :

To convert 7000 cubic centimeters (cm³) into liters (L), you need to understand the relationship between these two units of volume.

  1. Understanding the Conversion Factor:

    In the metric system, the conversion between cubic centimeters and liters is straightforward:

    [tex]1 \text{ L} = 1000 \text{ cm}^3[/tex]

  2. Performing the Conversion:

    Given that 1 liter is equivalent to 1000 cubic centimeters, you can calculate the number of liters in 7000 cm³ by dividing the volume in cubic centimeters by 1000:

    [tex]7000 \text{ cm}^3 \times \frac{1 \text{ L}}{1000 \text{ cm}^3} = 7 \text{ L}[/tex]

  3. Conclusion:

    Thus, 7000 cm³ is equivalent to 7 L. Therefore, the correct choice is:

    Option a) 7 L

By understanding the basic conversion between these units of volume, converting between them becomes a simple calculation. This knowledge is foundational in many areas of science and engineering, where volume measurements are required to be precise and consistent.
