Hi I have an odd question I will be making a few sheet cakes with 3 layers of cake I will cut 2" tall cake in half and triple layer a 12 x 18 cake, so each layer is 1/2" total of 3" of cake, how do I determine the servings for this cake just like 30 more servings? or what? not sure...I need to know how many of these I need to equal 250-270

thin layers of buttercream will fill these cakes.

The surface area is the same so you'll get the same number of servings. The servings will be taller, that's all.

If you cut them 2x2 square, you'll get 54 servings.
If you cut them 1x2xheight, you'll get 108 servings.

If the servings is 50% taller than a regular serving of cake, then be sure to charge 50% more. i.e. regular serving is 1x2x4 = 8 cubic inches @ $3/serving. OR ..... your servings will be 1x2x6 = 12 cubic inches (50% more cake) so price should be $4.50/serving (50% more price).
