Solution: Let x be the height of a student in Marta's class.

The mean height of 18 students in Marta's class is 60 inches

We know that:

$Mean = \frac{\sum x_{i}}{n}$

$60 = \frac{\sum x_{i}}{18}$

$60 \times 18 = \sum x_{i}$

$\sum x_{i} = 1080$

Therefore, the total measure of all 18 student's heights is 1080 inches
