Answer:
The height of the container is 4 feet.
Explanation:
A container has the format of a rectangular prism.
It has three dimensions: width(w), length(l), height(h).
The volume is:
![V = w*l*h](https://img.qammunity.org/2021/formulas/mathematics/college/52sogcvce38bft9efkd7fg52l39x8izyak.png)
In this question:
![w = 45, l = 50, V = 9000](https://img.qammunity.org/2021/formulas/mathematics/college/vlzxydx0pr0hte3oef1fna2gv53w7ruor8.png)
We have to find the height(length and width are in feet, volume in cubic feet, so the height will be in feet).
![V = w*l*h](https://img.qammunity.org/2021/formulas/mathematics/college/52sogcvce38bft9efkd7fg52l39x8izyak.png)
![9000 = 45*50*h](https://img.qammunity.org/2021/formulas/mathematics/college/14l0ju2399jvu53mszwjq81r15d5a869r5.png)
![h = (9000)/(45*50)](https://img.qammunity.org/2021/formulas/mathematics/college/10n8bg45f4sy15k1x3ysj4oh0r6fe6oefm.png)
![h = 4](https://img.qammunity.org/2021/formulas/mathematics/college/a4c3it2a9deekgs3kfaqyzck94al1iic37.png)
The height of the container is 4 feet.
