Answer:
[tex]V=40\ in^3[/tex]
Step-by-step explanation:
The graph is not attached, however we know that, the volume of a triangular pyramid is given by the formula
[tex]V=\frac{1}{3}Bh[/tex]
where
B is the area of the triangular face
h is the height of the pyramid
we have
[tex]B=12\ in^2\\h=10\ in[/tex]
substitute the given values
[tex]V=\frac{1}{3}(12)(10)=40\ in^3[/tex]
