Calculating Volume of Rectangular Prisms

Mr. Buffington introduces the concept of volume, explaining it as the amount of space inside a 3D object, measured in cubic units. He demonstrates how to calculate the volume of a rectangular prism using the formula length × width × height, emphasizing that the order of multiplication does not matter. The video includes practice problems to reinforce the concept, with a focus on understanding and applying the formula correctly.
