Answer:
[tex]307,572\ ft^{3}[/tex]
Step-by-step explanation:
we know that
The volume of a pyramid is equal to
[tex]V=\frac{1}{3}Bh[/tex]
where
B is the area of the base of the pyramid
h is the height of the pyramid
Find the area of the base B
[tex]B=114^{2}=12,996\ ft^{2}[/tex]
we have
[tex]h=71\ ft[/tex]
substitute the values
[tex]V=\frac{1}{3}(12,996)(71)=307,572\ ft^{3}[/tex]
