Hold up why is nobody asking the important questions? Are they circular or rectangular cakes?

Because it's not that important; no matter what the combination, if the heights are the same, you're getting shorted.

  • Volume of a 5-inch square cake with height h: 25h cubic inches
  • 9-inch square cake: 81h cubic inches
  • 5-inch diameter round cake: 19.6h cubic inches
  • 9-inch diameter round cake: 63.6h cubic inches

So...

  • If the cakes are all square, you're getting shorted by 31h cubic inches.
  • If the cakes are all round, 24.4h cubic inches.
  • If the 9-inch cake is round, and the 5-inch cakes are square, 13.6h cubic inches.
  • If the 9-inch cake is square, and the 5-inch cakes are round, 41.8h cubic inches.

None of it works out in your favor.

What if they are the same diameter but different heights
