In this video, we present a 3D working model on the Sectors of the Indian Economy, demonstrating the Primary, Secondary, and Tertiary sectors using cardboard, color paper, and miniature setups. This is a great commerce project for school exhibitions and helps in understanding how different sectors contribute to the economy.
