Final answer:
The comparison of volumes between Uranus and Neptune shows that the statement 'the volume of Uranus is less than ten times the volume of Neptune' is false.
Step-by-step explanation:
The statement that the volume of Uranus is less than ten times the volume of Neptune can be explored by comparing their respective volumes. According to the data, the volume of Uranus is 6.83 × 10^13 km^3, and the volume of Neptune is 6.25 × 10^13 km^3. To check the validity of the statement, we can divide the volume of Uranus by the volume of Neptune. The calculation shows:
Volume ratio = (6.83 × 10^13) / (6.25 × 10^13) ≈ 1.09
Since 1.09 is far less than ten, the statement is false. The volume of Uranus is not less than ten times the volume of Neptune; it's only slightly larger.
