Answer:
[tex]\large\boxed{V=226,200\ ft^3}[/tex]
Step-by-step explanation:
The formula of a volume of a prism:
[tex]V=BH[/tex]
B - area of a base
H - height
We have the triangle in the Base. The fomula of an area of a triangle:
[tex]A_\triangle=\dfrac{bh}{2}[/tex]
b - base
h - height
We have b = 58ft and h = 78ft. Substitute:
[tex]B=\dfrac{(58)(78)}{2}=(29)(78)=2,262\ ft^2[/tex]
The volume:
B = 2,262 ft², H = 100 ft. Substitute:
[tex]V=(2,262)(100)=226,200\ ft^3[/tex]
