Let's call the three consecutive even numbers as $x$, $x + 2$, and $x + 4$.

Given that the smallest of the three numbers is 120, we can set $x = 120$. Therefore, the three consecutive even numbers are:

$120, 122, 124$

To find their total, we simply add them:

$120 + 122 + 124 = 366$

Thus, the total of the three consecutive even numbers is 366.
