$$\left. \begin{array} { l } { V = \frac { A _ { b } \cdot h } { 3 } \quad A _ { B } = c \cdot c = c ^ { 2 } } \\ { = \frac { 18,1 \cdot 18,1 \cdot 21 } { 3 } } \\ { = 2293,27 mm ^ { 3 } } \\ { } \end{array} \right.$$

Solve for V, A_b, h, A_B

$$V=\frac{A_{B}A_{b}h}{3}$$

$$A_{b}\in \mathrm{R}$$

$$h\in \mathrm{R}$$

$$A_{B}\in \mathrm{R}$$
