The answer is 216 cubic feet. How? All you have to do is multiply every number then divide it by 2. Like this: 2*12*18=432. 432/2= 216 cubic feet.
In order to derive the base of a triangle from its area, you need its height as well.
In fact, if we solve the area formula for the base, we have

So, the base length would be

where h is the height relative to the base you're interested in.
