How is the flood a symbol/type representing baptism?

1 Peter 3:20 - 21

ESV - ²⁰ Because they formerly did not obey, when God's patience waited in the days of Noah, while the ark was being prepared, in which a few, that is, eight persons, were brought safely through water. ²¹ Baptism, which corresponds to this, now saves you, not as a removal of dirt from the body but as an appeal to God for a good conscience, through the resurrection of Jesus Christ.
