Volume of square based pyramids
The volume of a square based pyramid works on area of the base multiplied by height and some factor.
Base area of square based pyramid = `Len\g\th\times\width`
Volume of a square based pyramid = `1/3times\area\ of\ base\ timesheight`
Volume of a square based pyramid = `1/3times\l\e\n\g\th\times\width\timesheight`
3 square based pyramids fill 1 cube (with the same size base and height).
NOTE:
Areas shaded blue are all equal.
