Answer:
72 cubic meters
Explanation:
The volume is 72 because to find the volume of a rectangular prism, you multiply the length by the width by the height. The length is 9, the width is 4, and the height is 2. 9 times 4 times 2 is equal to 72, so the volume is 72 cubic meters. Remember to write cubic meters after your answer because volume is always represented in cubic units. If you just write your volume as 72 meters, it would be wrong, as it should be written as 72 cubic meters. With that, you get your final answer. I hope this helps!
