Explanation:

Step1: Identify prism dimensions

From the figure, the rectangular prism has length $l=5$, width $w=2$, height $h=3$.

Step2: Calculate volume

Volume formula: $V = l \times w \times h$
$V = 5 \times 2 \times 3$

Step3: Compute final value

$V = 30$ cubic units

Answer:

30 cubic units
