Explanation:
You can calculate volume of the rectangular prism with the following formula:
![V=Bh](https://img.qammunity.org/2020/formulas/mathematics/college/1z8biyc5dxidzjd7gaahhzli35rckolci0.png)
Where B is the area of the base and h is height of the prism.
The problem gives you the area of the base and the height, they are:
![B=125units^(2)\\h=5units](https://img.qammunity.org/2020/formulas/mathematics/middle-school/zlnujovj0nmux4cjay1oc2tqnpvxssj3by.png)
When you substitute values, you obtain the following result:
![V=125units^(2)*5units=625m^(3)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/nu66xkqko5jh2vaxln3l0ns9heyui9jau3.png)
