Tia made a two layer cake. Each layer is a rectangular prism that is 2 inch height. The base of the bottom layer is 100 square inches. The base of the top layer is 64 square inches. What is the total volume of the cake?

328 cubic inches.

Step-by-step explanation:

Given:

Tia made a two layer cake.

Each layer is a rectangular prism that is 2 inch height.

The base of the bottom layer is 100 square inches.

The base of the top layer is 64 square inches.

Question asked:

What is the total volume of the cake?

Solution:

First of all we will find volume of each layer cake and then add both of the volumes:-

Volume of bottom layer cake = Base of the cake height

                                                 =  100 square inches 2 inches

                                                 = 200 cubic inches

Similarly:-

Volume of top layer cake = Base of the cake height

                                          =  64 square inches 2 inches

                                          = 128 cubic inches

Total volume of the cake = Volume of bottom layer + Volume of top layer

                                          = 200 cubic inches + 128 cubic inches

                                          = 328 cubic inches

Thus, the total volume of the cake is 328 cubic inches.
