Answer:
The height is 2.25 meters. 
Step-by-step explanation:
The volume of a right rectangular prism is the product of the length, width, and height. So it would be V=w*l*h.
Because you have been given the values of the volume, width, and length, you can plug in those values into the equation to find the height. It should look like this: 43.875=5 * 3.9 * h
Then you can divide both sides of the equation by 5 * 3.9. 
So... 43.875/(5*3.9)=h
therefore h= 2.25. 
hope this explanation makes sense!
