Volume of a pyramid slant height h V = ⅓ A h The volume of a pyramid is found by multiplying the area of its base A by its perpendicular height h and dividing by 3. Apex A base Volume of a pyramid = ⅓ × area of base × height
Volume of a cone h or r V = ⅓ πr2h A cone is a special type of pyramid with a circular base. The volume of a pyramid can be found by multiplying the area of the base by the height and dividing by 3. The volume of a cone is given by: Volume = ⅓ × area of circular base × height
