To answer this question, we can count the number of the "small" cubes we have in the prism. One way of doing this is by noticing that we have:

1. As a length, we have 5 cubes.

2. As a width, we have 3 cubes.

3. As a height, we have 2 cubes.

And we can see this by checking the following sketch of the prism:

4. And now we can multiply the number of each of the sides of the prism. Therefore, the volume of the cube is then:


\begin{gathered} V_=2*5*3=30 \\ V=30 \end{gathered}

In summary, therefore, the prism has a volume of 30 cubic units.
