Answer: 11.7 lb
Explanation:
You know that the water in a tank weighs 731.25 lb and one cubic foot of water weighs 62.5 lb.
Therefore, to calculate the the cubic feet of water that the tank holds, you must divide the weight of the water in the tank by the weigth of a one cubic foot of water
Keeping this on mind, you have:
![x=(731.25lb)/(62.5lb)\\x=11.7lb](https://img.qammunity.org/2020/formulas/mathematics/college/dlp4ngjgs1hssrjvxjfsvs4ctt7vb7wxia.png)
