Answer: D. [tex]168\ m^3[/tex]
Step-by-step explanation:
We know that the volume of a prism is given by :-
[tex]V=\dfrac{1}{2}*\text{base area*height}[/tex]
Now, from the given picture, the dimensions of the base of the prism = [tex]7\ m\times8\ m[/tex]
Thus, Base Area =[tex]7\times8=56\ m^2[/tex]
Height of prism = 6 m
Therefore, the volume of the prism is given by ;-
[tex]V=\dfrac{1}{2}*56\times6=168\ m^3[/tex]
Hence, Volume of the given prism = [tex]168\ m^3[/tex]
