Answer:
55
Explanation:
To find the volume of the solid given, we first find its area nad the multiply it by the height to get the volume.
The area of the figure is
[tex]Area=2.5\cdot2+3\cdot2.5+(6-2.5)\cdot9=44[/tex]therefore, the volume is
[tex]\text{Volume}=44\cdot1.25=55[/tex]Hence, the volume of the solid is 55 cubic feet.
