Step-by-step explanation:

The question asks us to calculate the total number of marbles in a box that contains 19 large marbles and 20 small marbles, regardless of their color. This is a straightforward addition problem.

To find the total, we simply add the number of large marbles to the number of small marbles:

1. Number of large marbles: 19
