In the given images which values are needed in order to find the volume of the solid:3yd5yd2.5yd6ydBase Area:a.b.Height:a.

1) As we can see, this is a prism. Generally, the formula for the volume of a prism is the:
[tex]V=B_{Area}\times h[/tex]2) In that diagram, we can see the height is 2.5 yards and the base is made up of a rectangle.
So, we can write out this formula:
[tex]\begin{gathered} V=(6\times3)\times2.5 \\ V=45\:yd^3 \\ Base\:Area:18yd^2 \\ Height:2.5yd \end{gathered}[/tex]
