    Find the formulas for the volumes of a cube and a pyramid and write them here. Then we'll continue.

    You must be able to find the formulas you need. Do you have a text book?

    Ok, here are the formulas. \(\Large V_{cube} = s^3\) where s = side of cube \(\Large V_{pyramid} = \dfrac{1}{3}Bh\) where B = area of the base,. and h = height of the pyramid
