<button ng-click="cube()">X<sup>3</sup></button>
<p>Output: {{output}}</p>
var myApp = angular.module("myApp", []);
myApp.factory('CubeMathService', function() {
var factory = {};
factory.multiply = function(a, b, c) {
return a * b * c;
return factory;

myApp.service('CubeService', function(CubeMathService){
this.cube = function(a) {
return CubeMathService.multiply(a,a,a);
