...solid content is 6254725974-3748 cubic miles, . . . Ans. 2157 miles. 18. Kepler's third law is, that the squares of the periodic times of any two planets are to each other in the same proportion as the miles of their mean distances from the sun. The earth's periodic time is 365-256384 days, and that... | |
