Martin is using unit cubes to build a tower in the shape of a right rectangular prism. A description of the tower is listed below.

Bottom layer is made of 16 unit cubes

Bottom layer is in the shape of a square prism

9 more equal layers of unit cubes are added in top of the bottom layer

What is the total volume, in cubic units, of the competed tower?

144 cubic units.

Step-by-step explanation:

From the question, we are given the following values.

The bottom layer is made up of 16 unit cubes which comes in the shape of a square prism.

This means the bottom layer = the are of the base of the rectangular prism = 16 square units

From the question, we are also told that 9 more layers are added to the bottom layer of the rectangular prism. This means, the height of the rectangular prism = 9 units

The formula to find the volume of a rectangular prism = Area of the base * Height of the rectangular prism

Area of the base = 16 square units

Height of the rectangular prism = 9 units

Volume of the right rectangular prism = 16 square units * 9 units = 144 cubic units.

Therefore, the total volume, in cubic units, of the competed tower is 144 cubic units.
