Does anyone know how many servings in a cake carved in the shape of a number '4'?

I guess I could make it as big as I needed...but dont want it to look odd. It needs to serve about 35-40 ppl? What pan size should I use?

I was thinking of just having additional servings from cupcakes?

For that many servings I suggest you start with a 12x16x2 aka a 1/2 sheet.

If you don't think that is going to be enough you can double it (make it 4" high).  By the time you cut it into shape,  it would be just a bit more than you need.

Thanks so much!!!
