The volume of a rectangular prism can be calculated by using this formula:
![V=lwh](https://img.qammunity.org/2023/formulas/mathematics/high-school/75tmbnos9kuyj334ybmsvsgeropug62khi.png)
Where "l" is the length, "w" is the width and "h" is the height.
In this case, you know that the dimensions of the classroom are:
![\begin{gathered} l=32ft \\ w=26ft \\ h=9ft \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/u9he2sfaecjpx6u9ewzso5kjnge4rksie6.png)
Then, you can substitute values into the formula and then evaluate, in order to find the volume of the room:
![\begin{gathered} V=(32ft)(26ft)(9ft) \\ V=7,488ft^3 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/yat3xx1ofkmyggfztdcfg751qcj7hif19m.png)
The answer is:
![V=7,488ft^3](https://img.qammunity.org/2023/formulas/mathematics/college/pyegqryia29z2qddec724qzuwgpj7rogbj.png)
