Come up with a situation in which you would have to calculate the surface area or volume of a solid.

You are a civil engineer tasked with designing a water storage tank for a new housing development. The tank needs to have a certain volume to hold enough water for the residents, but it also needs to fit within a specific footprint on the construction site. In order to ensure that the tank meets these requirements, you must calculate both the surface area and volume of the tank in order to optimize its design and functionality.
