Hallo Anonymous,
$${\mathtt{V}} = {\mathtt{G}}{\mathtt{\,\times\,}}{\mathtt{h}}$$ => $${\mathtt{h}} = {\frac{{\mathtt{V}}}{{\mathtt{G}}}}$$ => $${\mathtt{h}} = {\frac{{\mathtt{35}}\left[{{dm}}^{{\mathtt{3}}}\right]}{{\mathtt{100}}\left[{{dm}}^{{\mathtt{2}}}\right]}} = {\mathtt{0.35}}{dm} = {\mathtt{3.5}}{cm}$$
Anmerkung: 35 l = 35 dm³ ; 1 m² = 100 dm² ; 1 dm = 10 cm
Das Wasser stand 3,5 cm hoch.
