Volume of rectangular based pyramids

The volume of a rectangular based pyramid works on area of the base multiplied by height and some factor.

To measure a rectangular based pyramid you need to multiply base and height then multiply another factor

Area of base of a rectangular based pyramid = $Len\g\th\times\width$

Volume of a rectangular based pyramid = $1/3times\area\ of\ base\ timesheight$

Volume of a rectangular based pyramid = $1/3times\l\e\n\g\th\times\width\timesheight$

3 rectangular based pyramids added together makes the same area as a cuboid

3 rectangular based pyramids fill 1 rectangular cuboid (with the same size base and height).

NOTE:

Areas shaded blue are all equal.
