You can't directly fit Earths into Venus because they are both spheres. It's like asking how many basketballs fit inside a soccer ball - it's not a simple comparison.

However, we can compare their volumes:

* Earth's volume: 1.08321×10^12 km³

* Venus's volume: 9.284×10^11 km³

Venus is slightly smaller than Earth, with about 85.6% of Earth's volume. This means you couldn't fit a whole Earth inside Venus, but you could fit a slightly smaller version of Earth inside Venus.
