To find volume, you'll just need to multiply the Length, Width, and Height. It's very simple. Let's go over it step-by-step.
Now, the formula is L × W × H. Like I've said before, it is very simple.
In this problem, 18 is the Length, 6 is the Width, and 16 is the Height.
We now have the Length, Width, and Height.
18 ⇒ Length
6 ⇒ Width
16 ⇒ Height
Let's multiply now.
18 × 6 × 16 = 1,728 in (Do not forgot the unit)
Therefore, the volume is 1,728 in.
