Around here, sheetcakes are double layer, filled. I'm making one for a preK class, so it will only be a single layer, which I've never done before. I

Could someone please confirm servings for a single layer 9x13 and 11x15? According to my math, I get 29 and 41, respectively. But my math could be faulty

How do you cut a cake to get 29 pieces? (29 is a prime number and is evenly divisible by 1 and 29 and that's it).

But your numbers are very close.

9x13, when cut in 2x2" squares, means you will cut the cake in approx 4 rows by 6 columns (24 servings). 11x15, means you will cut the cake in approx 5 rows by 7 columns (35 servings).

i've done tons of sheet cakes and i figured out that it all depends on the size of slices you cut. for example...a single layer, 12x18 can provide either 24, 36 or 54 slices. here's a picture so you can see.
