Answer:
4.5
Explanation:
Because we are trying to find the length, we are going to need to change the equation in order to isolate L.
You divide wh with v.
V/wh = L
Now, since the quantity of the volume is 138.24, we divide that by 9.6 x 3.2
Solve 9.6 x 3.2. This would give you 30.74.
Divide 138.24 by 30.74 and your answer should be 4.497...
Rounding that by the nearest 10th would get you 4.5!
