Does a 12x16 cake with 4" inch heigh is it enough to serve 100?

The nice ting about square or rectangle cakes is that you can do the math to figure the number of servings.

If you cut the cake in the industry standard of 1x2x4" pieces, that means this cake will be cut in 12 rows by 8 columns = 96 servings.

(A 2-layer 12x18 serves 10

Thanks, that a relief.
