The volume of the complex shape is 152 cu cm
Explanation:To find the volume of the composite figure, we need to find the volume of each shape that form the figure.
Volume of the square is:
[tex]\begin{gathered} v=a^2h \\ =8^2\times2 \\ =128\operatorname{cm}^3 \end{gathered}[/tex]Volume of rectangle is:
[tex]\begin{gathered} v=lwh \\ =3\times4\times2 \\ =24 \end{gathered}[/tex]Volume of shape is:
[tex]\begin{gathered} 128+24 \\ =152\operatorname{cm}^3 \end{gathered}[/tex]
