Answer:
The volume of the figure is [tex]8\ ft^{3}[/tex]
Step-by-step explanation:
we know that
The volume of a triangular pyramid is equal to
[tex]V=\frac{1}{3}BH[/tex]
where
B is the area of the base
H is the height of the pyramid
Find the area of the triangular base B
[tex]B=\frac{1}{2}(3)(4)=6\ ft^{2}[/tex]
we have
[tex]H=4\ ft[/tex]
substitute the values
[tex]V=\frac{1}{3}(6)(4)=8\ ft^{3}[/tex]
