The volume of the figure can be calculate by dividing the figure into 2 regular prisms.
Calculate the volume for each prism and add them together
for the prism to the left
[tex]\begin{gathered} V=l\cdot w\cdot h \\ V=3\cdot10\cdot7 \\ V=210c^{}m^3 \end{gathered}[/tex]
For the prism to the right
[tex]\begin{gathered} V=l\cdot w\cdot h \\ V=6\cdot10\cdot3 \\ V=180cm^3 \end{gathered}[/tex]
The total volume is the addition of both volumes
[tex]\begin{gathered} Vt_{}=180cm^3+210cm^3 \\ Vt=390cm^3 \end{gathered}[/tex]
