Radius r = 1080 meters. Volume of a sphere = (4/3) * pi * r^3 Surface area of a sphere = 4 * pi * r^2 We want to find x, some unit of measure. The volume of the sphere in units of x^3 is: ((4/3) * pi * r^3) / x^3 The surface area of the sphere in units of x^2 is: (4 * pi * r^2) / x^2 The problem states these are equal. So: ((4/3) * pi * r^3) / x^3 = (4 * pi * r^2) / x^2 (1/3) * r = x 360 = x
