The volume of a rectangular prism is given as:
![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 we have that the length is 3.2 ft, the width is 1.7 ft and the height is 2.1 ft; plugging this values in the expression for the volume we have:
![\begin{gathered} V=(3.2)(1.7)(2.1) \\ V=11.424 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/vi30e40jiy37gxy0govegmte4h1zp9i2hk.png)
Therefore, the volume of the prism is 11.424 cubic ft
