Answer:
So Prism D has the greatest volume.
Explanation:
Since volume of a triangular prism = A × h
where A = Area of base of prism
h = height
For prism (A) ⇒ Volume = ( 6 × 7 ) × 9
= 42 × 9 = 378m³
Prism (B) ⇒ Volume = ( 5 × 6 ) × 13
= 30 × 13 = 390m³
Prism (C) ⇒ Volume = ( 11 × 8 ) × 8
= 88 × 8 = 704m³
Prism (D) ⇒ Volume = ( 10 × 8 ) × 9
= 80 × 9 = 720m³
So prism D has the maximum volume.
