Answer:a good rule of thumb is to use 1 cup of frosting for each 8-inch layer, or 1.5 cups for each 9 or 10-inch layer. Assuming that the cake is a standard 2-layer cake, we can estimate that the height of the cake is approximately 4 inches. Therefore, if 1 inch of frosting belongs on 2 inches of cake, then we can estimate that 0.5 inches of frosting belongs on each inch of cake. Since there are 2.54 centimeters in an inch, we can estimate that 1 centimeter of cake would require approximately 0.197 inches of frosting. Therefore, we can estimate that approximately 0.0985 inches or 0.25 centimeters of frosting would belong on a centimeter of cake.
Please note that this is an estimation and may not be accurate for all cakes.
