The problem that can be solved by performing the multiplication \( 45 \times 58 \) is:
Min measured 45 inches of string. Min then measured another 58 inches of string. How many inches of string did he measure in all?
This quantitative problem involves adding two whole numbers (45 and 58); however, the multiplication could represent a larger context, such as repeated measurement or scaling. In various word problems, multiplying whole numbers is common for finding total quantities.
