Answer:
972 in³
Step-by-step explanation:
Let's treat the triangular end of this solid as the "base." Then the volume of this solid is V = (base)(length).
The area of the "base" as defined above is A = (1/2)(9 in)(12 in), or 54 in².
The length of the solid is 18 in.
To find the volume, multiply as explained above:
V = (base)(length), which here is:
V = (54 in²)(18 in) = 972 in³ (answer)
