The video tutorial explains how to determine the mass of one large brick given that six small bricks have the same mass as five large bricks. It starts by calculating the total mass of the small bricks, which is 15 kilograms, and then divides this by five to find the mass of one large brick, which is 3 kilograms. The tutorial emphasizes the importance of understanding the method and using times tables for calculations.
