Answer:
2,916 inches
Explanation:
The formula for volume is length x width x height.
So, you will have to start to identify each of these.
First, though, because of 1.5 being feet and not inches, you must convert.
1 foot = 12 inches, so 1/2 foot = 6 inches. Meaning, 12 + 6, which is 18 inches.
Now, you can solve: 18 x 18 x 9 = 2,916.
Hope this helps! :)
