Final answer:
The volume of the given rectangular prism is 54 cubic meters.
Step-by-step explanation:
The volume of a rectangular prism can be found by multiplying the length, width, and height of the prism. In this case, the base of the prism is 3 meters by 9 meters, and the height is 2 meters. To find the volume, multiply the length, width, and height together:
Volume = length x width x height
Volume = 3m x 9m x 2m = 54 cubic meters
