(([7, -1, 9] - [-1, 6, 7]) ⨯ ([3, 4, 2] - [-1, 6, 7]))·([2, 3, 4] - [-1, 6, 7]) / ABS(([7, -1, 9] - [-1, 6, 7]) ⨯ ([3, 4, 2] - [-1, 6, 7])) = - 1
Abstand I von ABD
(([7, -1, 9] - [-1, 6, 7]) ⨯ ([1, 2, 3] - [-1, 6, 7]))·([2, 3, 4] - [-1, 6, 7]) / ABS(([7, -1, 9] - [-1, 6, 7]) ⨯ ([1, 2, 3] - [-1, 6, 7])) = 1
Die Abstande betragen 1 LE.
So machst du das auch mit den anderen Seitenflächen
Volumen
V = 1/6 * (([7, -1, 9] - [-1, 6, 7]) ⨯ ([3, 4, 2] - [-1, 6, 7]))·([1, 2, 3] - [-1, 6, 7]) = - 27
Das Volumen beträgt 27 VE
