Just a heads up: Earlier in the video I think the math is wrong in your chart... In the table you created, surface area increases more rapidly than volume, which is not the concept that you explain in your later section. You state clearly that as a cell increases in size, it's volume increases much faster than it's surface area, creating a lack of efficiency for a cell. By the math, something cubed would increase exponentially in comparison with something squared. Just thought I would throw it out there in case anyone hadn't done the math themselves on the chart. surface area= base x height volume= length x height x width
He did it completely correct, the volume was growing cubically instead of quadratically, as the surface area was. He wanted to show the definite trend that it was experiencing as the size of the cubes increased. To do this, he used smaller numbers, since they had the greatest surface area to volume ratios. When you get into larger cell sizes, the values for the volume exceed those of the surface area, making the data harder to show a trend TL;DR He was right, he set it up to show a trend, no words were used incorrectly
