The video tutorial explains how to calculate the volume of air in a shed shaped like a cuboid surmounted by a half-cylinder. It provides the dimensions of the cuboid and the half-cylinder, and details the space occupied by machinery and workers. The tutorial walks through the process of calculating the total volume of the shed, then subtracts the space occupied by machinery and workers to find the volume of air. The final result is approximately 827.15 cubic meters of air.
