Answer:
Option C. 6872.8 yd³
Explanation:
Since volume of the triangular prism = Area of square base × height of prism
Area of square base = length × width = 16×31 = 496 yd²
Height of the prism (By Pythagoras theorem) = Height of the isosceles triangle =
![\sqrt{(16^(2)-8^(2))}= √(256-64)](https://img.qammunity.org/2019/formulas/mathematics/high-school/d4h5tbhfm81xksg9m2zmkabzsray7rupqy.png)
=
![√(192)](https://img.qammunity.org/2019/formulas/mathematics/high-school/k28xxv5m394plbwjpi4smqqheh450mxiyz.png)
=
yd
Now we put these values in the formula of volume
Volume = 496×8√3 = 496×(13.86) = 6872.8 yd³
Answer is option C. 6872.8 yd³
