2.71×10–1 cm3
B
207.2 km2
C
5.81×105 m3
D
582.28 mm
Verified step by step guidance1
Understand that the SI unit for volume is the cubic meter (m^3).
Convert each given option to cubic meters (m^3) to determine which one is in the correct SI unit.
For the first option, 2.71×10^(-1) cm^3, convert cubic centimeters to cubic meters using the conversion factor: 1 cm^3 = 1×10^(-6) m^3.
For the second option, 207.2 km^2, recognize that this is an area measurement, not a volume, and thus cannot be converted directly to m^3.
For the fourth option, 582.28 mm, convert millimeters to meters using the conversion factor: 1 mm = 1×10^(-3) m, and then consider the volume context if applicable.
