I been thinking if these volume formulas are correct.
volume of a cube and Rectangular prism: Length* Width* Height

volume of a pyramid general formula: area of the base* height* 1/3 as a fraction.
volume of a pyramid with a rectangular base: length of base* width of base* height (of the pyramid) * 1/3 as a fraction.

can u also explain as simplist as u can the volume of a sphere, cone, cylinder, and a triangular prism? thanks a lot guys! :)
