In this video tutorial from Rura Math, the instructor demonstrates how to multiply polynomials to find the volume of a rectangular solid. The process involves multiplying three polynomials: (5x - 3), (2x + 3), and (x + 4). The instructor explains the multiplication step-by-step, first multiplying two polynomials and then incorporating the third. The final polynomial representing the volume is derived, and the instructor emphasizes that the order of multiplication does not affect the result. The video concludes with a call to action for viewers to subscribe and follow for more content.
