Question

4 fill in the blanks to tell about the rectangular prism below. this rectangular prism has _ layers and _ unit cubes in each layer. it has a volume of _ cubic units.

Explanation:

Step1: Count the layers

By observing the rectangular - prism, we can see there are 2 layers.

Step2: Count unit - cubes per layer

Each layer has 4 rows and 2 columns of unit - cubes. So the number of unit - cubes in each layer is \(4\times2 = 8\).

Step3: Calculate the volume

The volume \(V\) of a rectangular prism is the number of unit - cubes, which is the number of layers times the number of unit - cubes per layer. So \(V=2\times8 = 16\) cubic units.

Answer:

This rectangular prism has 2 layers and 8 unit cubes in each layer. It has a volume of 16 cubic units.
