A wedding cake has two layers as shown. Each layer is in the shape of a cube. The bottom of the cube and the area where the two cakes meet are not frosted. How much of the cake is frosted?

All of it because there is only two layers and where the two cakes meet are not frosted so that means the cake is not frosted

Answer: 680

Step-by-step explanation:

1. Find the smaller cake first with (lw*amount of sides) and then add it to the larger cake using the same formula.

6*6*6+10*10*6

This equals 816

2. Find the amount not frosted. The bottom and the connection. Simply, (lw).

6*6+10*10

This equals 136

3. Subtract 136 from 816.

816-136 = 680 sq inches
