To understand the formula, Linking a formula to a visualized image or physical object is Very helpful. For this aim, we developed 3D model. Step 01. Tinkercad modeling [Code block] Step 02. [Enjoy visualization with images] Load all pieces into the workspace. Now all the pieces stay together in Tinkercad's 3D design workplane. The images upper shows cube blocks of length 1, 2, 3, 4, and 5. On th..
