How many 9x13's would it take to feed 600 people a 1x1 single sample of cake?
Thanks in advance
There are a number of charts you could use. You can get anywhere from 45-50 slices for a 1"x2". So times the servings by 2 if you only want a 1".
You would get anywhere from 90-100 1"wide x 1"long servings for a 9x13.
You would then need 6-7 9x13 cakes for 600 servings. I would personally go with 7.
