Answer:

Let’s assume that the average height of someone who ask meaningless and questions is 5′7″ or 1.7 metres

and their average width is 1′8″ or 0.51 metres

Then 10/1.7 will allow you to get approximately 5.9 people lengthwise, and 19.6 crosswise

and 19.6 x 5.9 = 115.76 people

Here is a group of people practising the lengthwise position.
