Calculating Volume of Decomposed Shapes

The video tutorial explains how to calculate the volume of a figure using unit cubes. It begins by introducing the figure and encourages viewers to think about the problem. The tutorial then demonstrates breaking the figure into parts, calculating the volume of each part, and summing them up. An alternative method is also presented, which involves counting unit cubes in layers. The total volume is confirmed to be 36 cubic units.
