Zerteile zuerst den Körper in Quader.

Oberster Quader:$V_{\text{Quader oben}}=3\text{ cm}\cdot 4\text{ cm}\cdot 3\text{ cm}=36{\text{ cm}}^{3}V\_\{\backslash text\{Quader\; oben\}\}\; =\; 3\backslash text\{\; cm\}\backslash cdot4\backslash text\{\; cm\}\backslash cdot3\backslash text\{\; cm\}=36\backslash text\{\; cm\}^3$

Mittlerer Quader: $V_{\text{Quader Mitte}}=11\text{ cm}\cdot 3\text{ cm}\cdot 4\text{ cm}=132{\text{ cm}}^{3}V\_\{\backslash text\{Quader\; Mitte\}\}\; =\; 11\backslash text\{\; cm\}\backslash cdot\; 3\backslash text\{\; cm\}\backslash cdot4\backslash text\{\; cm\}=132\backslash text\{\; cm\}^3$

Unterer Quader: $V_{\text{Quader unten}}=3\text{ cm}\cdot 4\text{ cm}\cdot 2\text{ cm=24}{\text{ cm}}^{3}V\_\backslash text\{Quader\; unten\}\; =\; 3\backslash text\{\; cm\}\backslash cdot4\backslash text\{\; cm\}\backslash cdot\; 2\backslash text\{\; cm=24\}\; \backslash text\{\; cm\}^3$

Jetzt musst du nur noch alle Volumen miteinander addieren.
