Answer:
Step-by-step explanation: Break the shape up into two rectangles.
The first rectangle will be 5 x 7 x 3 yd cubed. The Volume of a rectangle is V=length x width x height so V=3 x 7 x 5, V=105 yds ^3
The second rectangle is 6 x 3 x 3 yd so the V=6 x 3 x 3yd ^3=54 yds^3
Add them together V=105+54=159 Yds^3
