Answer:
V = 432 m³
Step-by-step explanation:
The volume (V) of a prism is calculated as
V = Ah ( A is the area of the base and h the height )
A = bh ( area of triangular base, with b the base, h the perpendicular height)
Here b = 16 and h = 6 , then
A = × 16 × 6 = 8 × 6 = 48 m²
Then
V = 48 × 9 = 432 m³
