3D Shapes: Finding the Total Length

The video tutorial explains how to calculate the total length of straws used in a cuboid model. It begins by identifying the dimensions of the straws for height, length, and width. The instructor then demonstrates the step-by-step process of calculating each dimension separately using multiplication. Finally, the total length is obtained by adding the calculated values for height, length, and width. The tutorial emphasizes the importance of showing the method to earn full marks.
