alleryVolume of parallelepiped formed by ā, b̄, c̄:
A|(ā × b̄)·c̄|
B|ā + b̄ + c̄|
Cā·(b̄ + c̄)
D|ā||b̄||c̄|
Answer & Solution
Correct answer: A. |(ā × b̄)·c̄|
Volume = |(ā × b̄)·c̄| = |scalar triple product|.
The absolute value because volume must be positive
the sign of the scalar triple product depends on the orientation of vectors.
