I need to know how to find the contents of a sphone; however I have not been able to find an equation for it online. I noted that the equation for a cone is 1/3(h)(A base). So I thought that perhaps the formula for a sphone could be the volume of its base * h * 1/3 since a sphone is a continuous series of spheres terminating to a point similar to the continuous circles terminating to a point in a cone.
