Suppose that the volumes of four stars in the Milky Way are 2.7 × 10^18 km^3, 6.9 × 10^12 km^3, 2.2 × 10^12 km^3, and 4.9 × 10^21 km^3. What is the order of the stars from least to greatest volume?
To determine the order of the stars from least to greatest volume, we need to compare their volumes.
1. 6.9 × 10^12 km^3
2. 2.2 × 10^12 km^3
3. 2.7 × 10^18 km^3
4. 4.9 × 10^21 km^3
Therefore, the order of the stars from least to greatest volume is:
2.2 × 10^12 km^3, 6.9 × 10^12 km^3, 2.7 × 10^18 km^3, 4.9 × 10^21 km^3.
