Final answer:
Jupiter's volume can fit about 1,300 Earths.
Step-by-step explanation:
Jupiter, the giant among giants, has enough mass to make 318 Earths. Its diameter is about 11 times that of Earth (and about one tenth that of the Sun). Jupiter's average density is 1.3 g/cm³, much lower than that of any of the terrestrial planets. Jupiter's material is spread out over a volume so large that about 1,300 Earths could fit within it.
