The volume of the triangular prism is the Area of the base times the height
the area of the base is:
[tex]\frac{ab}{2}[/tex]
and the volume is:
[tex]V=(\frac{ba}{2})h[/tex]
now b=10 yards, a=20 yards, and V=600 yards^3
we clean the height
[tex]h=\frac{2V}{ab}=\frac{2\cdot 600}{10\cdot 20} = 6
[/tex]
the answer is height = 6 yards
