ball falls freely from a high place, and the height of each bounce after hitting the ground is (2/5) of the height of the previous drop. If the ball falls from a height of 125 meters, what is the height of the third bounce?
小球从高处自由落下，每次接触地面后弹起的高度是前一次下落高度的(2/5)．如果小球重125米高处落下，那么第三次弹起的高度是多少米？

<output>2/5 = around 0.4</output>

<gadget id="calculator">125 * (2/5) * (2/5) * (2/5)</gadget>
<output>8</output>
