 <p itemrel="description" style="margin:12px">Because the square is the basis of area calculation. That is why we use square units. 
 <br>
 The only problem with that was that the circle is not square. I have figured that the circle can be cut into four and then I get four right angles that can be aligned with the vertices of a square.

However, I have measured its length and width to make sure and I found that its real volume is about 10% larger. I took that into account in the calculations.

 <p itemrel="description" style="margin:12px">First I made a mistake in that. I knew that the height has to be divided by 2, not 3 as they usually do it, but I confused the vertical height with the slant height and I divided it by 2 only once, instead of twice. That resulted in an error.

My volume formula for a cone and a pyramid was undeveloped and I didn't have much web development skills but I had to start somewhere. My attention was divided by lots of details in both geometry and IT.
