The video tutorial explains how to calculate the surface area of a cylinder using its net. It begins by transferring the cylinder's measurements to the net, including the radius and height. The tutorial then demonstrates how to calculate the circumference of the circular parts of the cylinder. Finally, it shows how to calculate the surface area of each part and sum them to find the total surface area.
