The video tutorial explains how to solve volume problems using fractional edge lengths and unit cubes. It begins by reviewing the volume formula for rectangular prisms and then introduces a complex problem involving fractional cubes. The tutorial demonstrates how to calculate the volume of a cube with fractional side lengths and find the volume of a larger rectangular prism. Finally, it shows how to divide these volumes to determine how many smaller cubes fit into the larger prism.
