The ball falls from a height of 25 meters, bounces after landing, falls again, and bounces again. If the height of each bounce is (2/5) of the drop height, find the height of the third bounce of the ball.

<gadget id="calculator">2 / 5</gadget>
<output>2/5 = around 0.4</output>

<gadget id="calculator">25 * (2/5) * (2/5) * (2/5)</gadget>
<output>8/5 = around 1.6</output>

<result>8/5 = around 1.6</result>
