Step-by-step explanation:
When looking at the exterior of a building, we can often get clues about its interior functions. For example, the size and number of windows can indicate the amount of natural light inside and the purpose of the spaces. The use of buttresses on the exterior can reveal structural support for heavy roofs or vaulting. Additionally, architectural styles and decorative elements on the exterior can give us hints about the building's purpose and cultural influences.
