Finding Volume of Rectangular Prisms by Packing with Unit Cubes

The video tutorial explains how to find the volume of a rectangular prism and a cube using unit cubes. It begins with an introduction to volume, defining it as the number of cubic units needed to fill a space. The tutorial demonstrates calculating the volume of a cube by packing it with unit cubes and verifying the result using the traditional method of cubing the side length. It then applies the same method to a rectangular prism, showing how to determine its volume by analyzing its layers and verifying the result with the formula for volume.
