Victoria Falls (or Mosi-oa-Tunga, “the smoke that thunders”) is the world’s tallest waterfall. In the dry season it has a minimum volume rate of flow of 300 \(m^3/s\), and splits into 5 waterfalls along its 1708 \(m\) length. The highest of these is called Rainbow Falls, standing 108 \(m\) tall.
If 64.9 \(m^3/s\) of water flows over Rainbow falls, by the time it reaches the bottom of Rainbow Falls, what cross-sectional area does this water have? (Please make the likely unreasonable assumptions that none of the water evapourates, and that it stays together as its area decreases).
Please enter in a numeric value in \(m^2\).
