Answer:
[tex]h=10\ yd[/tex]
Step-by-step explanation:
we know that
The volume of the triangular prism of the figure is equal to
[tex]V=Bh[/tex]
where
B is the area of the triangular base
h is the height of the triangular prism
Find the value of B
[tex]B=\frac{1}{2}(6)(3)=9\ yd^{2}[/tex]
we have that
[tex]V=90\ yd^{3}[/tex]
substitute the values and solve for h
[tex]90=9h[/tex]
[tex]h=90/9=10\ yd[/tex]
