An 8 inch square cake can reasonably be divided into 4 pieces, each of which will be 4 inches square.

A ten inch cake feeds about 12 people if you cut it in wedge like triangles, like a pizza. However if you go to wilton.com and look at the cutting guide, they say it feeds 38, realisticly, more like 30. That is if it is at least 2 layers. and those are uniform peices so everyone gets the same amout of cake. I like this way. it makes the cake go farther and no one eats half a piece and throws away the rest. and if people want more they can always go get another piece.
An entire village in South Africa.
About 12 people if it is part of a 3 veg meal.
You should order for only 90% of your guests. Some people will not eat the cake. So again, only order for 90% - in your case that means 12 people or one cake box mix - or one 9 inch round/square cake.
An 18-pound turkey will feed quite a few people. 18 pounds should feed about 12 people, with other side dishes being served.
10 to 12 people presuming you are serving other things with it.
i would say about 8 to 12 people depending if they are starving or not
about 16 people. If they are big eaters, 12 people.
I would make 12 pounds
Normally 12-16 slices but it depends on the sise of the cake.
