Hallo BI,
Länge l , Breite b und Höhe h in cm
Die Begrenzungsflächen sind Rechtecke:
i * b = 800 G1
l * h = 475 G2
b * h = 608 G3
G1 : G2
b/h = 800/475 = 32/19 → b = 32/19 * h
b in G3
32/19 * h2 = 608 | * 19/32
h2 = 608 * 19/32 = 361 | √
→ h = 19 [cm]
h in G2 → 19 * i = 475 → l = 25 [cm]
h in G3 → b * 19 = 608 → b = 32 [cm]
Gruß Wolfgang
