Du benötigst folgendes Grundwissen: Quader und Pyramide.

$V_{\text{Quader}}=l\cdot b\cdot h=G\cdot hV\_\{\backslash text\{Quader\}\}=l\backslash cdot\; b\backslash cdot\; h=G\backslash cdot\; h$

$V_{\text{Pyramide}}={\displaystyle \frac{1}{3}}\cdot G\cdot hV\_\{\backslash text\{Pyramide\}\}=\backslash dfrac\{1\}\{3\}\backslash cdot\; G\; \backslash cdot\; h$

=> $V_{\text{Pyramide}}={\displaystyle \frac{1}{3}}\cdot V_{\text{Quader}}V\_\{\backslash text\{Pyramide\}\}=\backslash dfrac\{1\}\{3\}\backslash cdot\; V\_\{\backslash text\{Quader\}\}$

$V_{\text{Pyramide}}={\displaystyle \frac{1}{3}}\cdot 42=14.V\_\{\backslash text\{Pyramide\}\}=\backslash dfrac\{1\}\{3\}\backslash cdot\; 42=14.$

Das Volumen der Pyramide beträgt $14c{m}^{3}14cm^3$.
