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

Answer 1

A construction company needs to pour a certain amount of concrete to create a foundation for a building. In order to determine how much concrete they need, they must calculate the volume of the foundation. They also need to calculate the surface area of the forms (wood frames) that will hold the concrete in place, to calculate the cost of materials needed to create those forms.
