The video tutorial explains how to calculate the volume of different 3D shapes: cones, cylinders, and spheres. It starts with the formula for the volume of a cone, using a specific example to demonstrate the calculation. The tutorial then moves on to describe the formula for the volume of a cylinder, highlighting the differences from the cone's formula. Finally, it covers the formula for the volume of a sphere, emphasizing the need for only the radius in the calculation. The video aims to equip viewers with the knowledge to find the volume of these solid figures using the appropriate formulas.
