I'm having trouble with this and am unsure what I'm doing wrong. Let's use Earth as an example.
Volume = mass / density.
The calculation gives me a result of 1,086,109,090,909,090,000,000,000.00 (1.09E+24) m3. However, the Earth's volume is 1,083,210,000,000,000.00 m3. That's a 1 billion times difference.
Is there a discreprancy with the units this question advised to always use kg and m2?
