Not sure what kind of comment the question is expecting. Perhaps that the volume is in cubic mm? Also the video made no mention of taking steps to show that the x value actually generated a max volume. That can be done by finding V''(19.619), which is negative, hence generates a max volume. desmos.com/calculator/xblpuktvkz
