According to the image, we have to find the volume of a composite figure. As you can observe, it's formed by 2 figures where the volume of each of them follows the following rule: V = w x l x h.
In other words, we just need to multiply.
[tex]\begin{gathered} V_1=12m\cdot5m\cdot8m=480m^3 \\ V_2=22m\cdot5m\cdot8m=880m^3 \end{gathered}[/tex]
Then, we add these volumes to find the total.
[tex]V_{\text{total}}=480m^3^{}^{}+880m^3^{}=1,360m^3[/tex]
Hence, the volume of the figure is 1,360 cubic meters.
