Problem Statement

A container in the shape of a right circular cone is 12 inches tall and its base has a 5-inch radius. The liquid that is sealed inside is 9 inches deep when the cone is held with its point down and its base horizontal. When the liquid is held with its point up and its base horizontal, the liquid is mnp3,m-n\sqrt[3]{p}, where m,m, n,n, and pp are positive integers and pp is not divisible by the cube of any prime number. Find m+n+p.m+n+p.
