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 go lume, 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.
