To find the number of possible outcomes when tossing three 6-sided dice, we need to calculate the total combinations that can occur with three dice, each having 6 faces.

Each die has 6 possible outcomes (1 through 6). Since the rolls are independent of each other, we multiply the outcomes of each die:

$6 \times 6 \times 6 = 6^3 = 216$

Thus, there are 216 possible outcomes when tossing three 6-sided dice.

Tip: When calculating possible outcomes with independent events, multiply the number of outcomes for each individual event.
