Final answer:
The correct option is 0.000000113 km³.
The volume of a room that is 113 cubic meters (m³) can be converted to cubic kilometers (km³) by dividing by 1 billion, giving a result of 0.000000113 km³.
Step-by-step explanation:
The bedroom has a volume of 113 m³, and to convert this to cubic kilometers (km³), we need to understand the relationship between these two units of volume. The first step is recognizing that 1 km is equal to 1,000 meters. Therefore, to convert cubic meters to cubic kilometers, we raise this conversion factor to the third power (since volume is a measure with three dimensions - length, width, and height), which results in 1 km³ being equal to 1,000³ (or 1 billion) cubic meters.
To convert 113 m³ to km³, you divide the number of cubic meters by 1 billion since there are 1 billion cubic meters in one cubic kilometer. The calculation is as follows: 113 m³ / 1,000,000,000 m³/km³ = 0.000000113 km³. Therefore, the correct volume in cubic kilometers for a room with 113 m³ is 0.000000113 km³, which corresponds to option 1).
