The answer to this question is B
By definition, the volume of a rectangular prism is given by:
![V = (w) * (l) * (h) ](https://tex.z-dn.net/?f=V%20%3D%20%28w%29%20%2A%20%28l%29%20%2A%20%28h%29%0A)
Where,
w: width
l: length
h: height
Substituting values we have:
![4x ^ 8 + 3x ^ 6 = (x) * (x) * (h) ](https://tex.z-dn.net/?f=4x%20%5E%208%20%2B%203x%20%5E%206%20%3D%20%28x%29%20%2A%20%28x%29%20%2A%20%28h%29%0A)
Rewriting we have:
![4x ^ 8 + 3x ^ 6 = x^2 * (h) ](https://tex.z-dn.net/?f=4x%20%5E%208%20%2B%203x%20%5E%206%20%3D%20x%5E2%20%2A%20%28h%29%0A)
Clearing h we have:
![h = \frac{4x ^ 8 + 3x ^ 6 }{x ^ 2}](https://tex.z-dn.net/?f=h%20%3D%20%5Cfrac%7B4x%20%5E%208%20%2B%203x%20%5E%206%20%7D%7Bx%20%5E%202%7D%20)
Then, for power properties we have:
Answer:
The heigh of the box is:
