Summing Squares Geometrically

This is a short, animated visual proof of the formula that computes that sum of the first n squares using 6 copies of the sum of squares pyramids to build a rectangular prism . Here is a slower version of this video: Here are three other visual proofs about the sum of squares formulas: This animation is based on a visual proof by Man-Keung Siu from the March 1984 issue of Mathematics Magazine (), page 92.
