Answer:
V = 306.9 m³
Step-by-step explanation:
The formula of a volume of a prism:
[tex]V=BH[/tex]
B - base area
H - height
In the base we have the right triangle.
The formula of an area of a righ triangle
[tex]A=\dfrac{ab}{2}[/tex]
a, b - legs
We have a = 6.2m and b = 11m. Substitute:
[tex]B=\dfrac{(6.2)(11)}{2}=34.1\ m^2[/tex]
The height H = 9 m.
Substitute to the formula of a volume:
[tex]V=(34.1)(9)=306.9\ m^3[/tex]
