What is the volume of the prism?

cubic units

The volume of a rectangular prism is equal to the total number of unit cubes in the prism.

You can find the volume by multiplying the number of unit cubes in each layer by the number of layers.

You want to find the volume of the rectangular prism. First, find the number of cubes in one layer.

There are 2 rows of unit cubes with 5 cubes in each row.

So, there are 10 unit cubes in each layer.

Now, count the layers. There are 3 layers of unit cubes.

Multiply the number of unit cubes in each layer by the number of layers to find the prism's volume.

So, the volume of the prism is 30 cubic units.
