Given the figure of a prism
The volume of the prism = area of triangular base times the height of the prism
As shown:
The area of the triangular base =
[tex]\frac{1}{2}\cdot6\cdot3=3\cdot3=9m^2[/tex]The height of the prism = 7 m
So, the volume = 9 * 7 = 63 squared meter
So, the answer will be option D) 63 m^3
