I had a toy when I was a kid that took 6 AA batteries. Now I know that means it wanted around a 9V input. But why did it take 6AAs instead of one 9V? The 9V would’ve been smaller and lighter, wouldn’t that have let them make a smaller battery compartment and save on manufacturing costs?

A 9V battery usually **is** a stack of 1.5V cells. There is no difference, with the obvious caveat that 6AAs will have a significantly larger combined capacity than a 9V block.
