SUMMARY
The volume of a parallelepiped defined by vectors u, v, and w is calculated using the formula |u · (v × w)|, where "·" denotes the dot product and "×" denotes the cross product. The discussion emphasizes understanding that the dot product of two vectors represents the area of a parallelogram, and the height of the parallelepiped is determined by the projection of a vertical line onto the plane orthogonal to the two vectors. This geometric interpretation is crucial for solving related problems in linear algebra.
