The length of rectangular prism is l = 20 m.
The height of trianguar prism is h = 2 m.
The width of triangular prism is w = 7 m.
The formula for the volume of triangular prism is,
![V=l\cdot w\cdot h](https://img.qammunity.org/2023/formulas/mathematics/college/3q2zwvs64f3ti00knxr5crf2fis1f7mjho.png)
Determine the volume of triangular prism.
![\begin{gathered} V=20\cdot2\cdot7 \\ =280 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/6hlmke7xccv0lalzgw662olqy49hldjlej.png)
So answer is 280 cubic meter.
