SUMMARY

The discussion focuses on calculating the scalar triple product of three vectors to determine the volume of a parallelepiped. The vectors provided are (2î + 3j + 4k), 4j, and (5j + mk). To achieve a volume of 24, the value of m must be calculated using the formula for the scalar triple product, defined as ##\vec u \cdot (\vec v \times \vec w)##. The correct application of this formula is essential for solving the problem accurately.

Homework Statement


The edges of a parallelopiped are given by the vectors (2î + 3j^+ 4k^), 4j^ and (5j^ + mk^). What should be the value of m inorder that the volume of the parallelopiped be 24?

Homework Equations

The Attempt at a Solution


Volume of the parallelopiped is the scalar triple product of three vectors. I want to know the formula or method of finding dot product of three vectors.

The scalar triple product is not a dot product of three vectors, it is ##\vec u \cdot (\vec v \times \vec w)##.
