Explanation:
Recall the formula for the volume of a prism:
![Vol=W\,*\,D\,*\,H](https://img.qammunity.org/2021/formulas/mathematics/middle-school/kjr8tvohfqva4cn0dob560q37mdxp36m9k.png)
where W represents the prism's width, D its depth, and H its height.
In your case the prim is in fact a cube because the three dimensions above are equal (all of them are 6 yards)
Then the volume of this prism is:
![Vol=W\,*\,D\,*\,H\\Vol= 6\,yd\,*\,6\,yd\,\,*\,6\,yd\,\\Vol= 216\,\,yd^3](https://img.qammunity.org/2021/formulas/mathematics/middle-school/yao363wdltccu744e7fpd55713twco3x4d.png)
