Answer:
A. (0, 5)
Step-by-step explanation:
Physically speaking, the volume of the box and the side of the square cutout are positive value. So that the following inequations must be satisfied:
(1)
(2)
(3)
From (1), (2), (3) we find that:
(1):
![h > 0](https://tex.z-dn.net/?f=h%20%3E%200)
(2):
![16 > 2\cdot h](https://tex.z-dn.net/?f=16%20%3E%202%5Ccdot%20h)
![8 > h](https://tex.z-dn.net/?f=8%20%3E%20h)
![h < 8](https://tex.z-dn.net/?f=h%20%3C%208)
(3):
![10 > 2\cdot h](https://tex.z-dn.net/?f=10%20%3E%202%5Ccdot%20h)
![5 > h](https://tex.z-dn.net/?f=5%20%3E%20h)
![h < 5](https://tex.z-dn.net/?f=h%20%3C%205)
We see that equation above is the multiplication of a first grade monomial and two first grade binomials, which means that:
![h > 0 \,\land\,h < 5\,\land\,h< 8](https://tex.z-dn.net/?f=h%20%3E%200%20%5C%2C%5Cland%5C%2Ch%20%3C%205%5C%2C%5Cland%5C%2Ch%3C%208)
![0< h < 5](https://tex.z-dn.net/?f=0%3C%20h%20%3C%205)
In other words, the reasonable domain for this situation is A.
