Final answer:
The ancient city of Mohenjo-Daro featured sophisticated urban planning with facilities like a large public bath, granary, and multistory residences indicating an advanced society. The bath was forty feet by twenty-three feet, the city had a granary for crop storage, and homes had central courtyards with innovative wind-cooling systems.
Step-by-step explanation:
The sizes of structures at Mohenjo-Daro, an ancient Indus Valley civilization, indicate a sophisticated level of urban planning and social organization. For instance, the public bath at Mohenjo-Daro measured an impressive forty feet long and twenty-three feet wide, which would be approximately 12.2 meters by 7 meters. This public bath was entered by staircases on both sides and was provided with water from a nearby well. Other architectural accomplishments include a large hall supported by pilasters and multistory residences that suggest a complex social hierarchy within the city. The overall granularity in planning is also evident from the Great Enclosure, as well as the lower city where the residential areas were equipped with wells and bathrooms.
The granary found at Mohenjo-Daro suggests a system of surplus crop storage, indicating a well-organized societal structure with an economy based on agriculture. Houses typically consisted of four to six rooms built around a central courtyard, reflecting the practicality that characterized the Indus Valley civilization. The existence of wind devices for cooling buildings also showcases the ingenuity of the residents of Mohenjo-Daro, who were far ahead of their time in urban planning and engineering.
