Scalar Triple Product As Volume
Three vectors from a common vertex sweep out a parallelepiped, and the animation shows how the cross product of two vectors gives a base area (as a vector perpendicular to that face), while the dot product with the third vector projects it to find the height. Multiplying area by height yields the volume, matching the determinant formula. Useful for Class 12 students studying vectors and determinants together.
