Spawn Physics Object on Enemy Death

I have a cube enemy that attacks the character. When the character kills the enemy I’d like the enemy to die and for there to be say a 9x9x9 cube of smaller cubes with an outward force that would simulate it being broken into smaller pieces, and then after a short time, they disappear. I need help figuring out how to do this, I’m fairly new so sorry if it’s obvious. Thanks!
