What will be the output of the following C++ code? #include using namespace std; class Box double length; double breadth; double height; public: double getVolume(void) return length * breadth * height; void setLength( double len ) length = len; void setBreadth( double bre ) breadth = bre; void setHeight( double hei ) height = hei; Box operator+(const Box& b) Box box; box.length = this->length + b.length; box.breadth = this->breadth + b.breadth; box.height = this->height + b.height; return box; ; int main( ) Box Box1; Box Box2; Box Box3; double volume = 0.0; Box1.setLength(6.0); Box1.setBreadth(7.0); Box1.setHeight(5.0); Box2.setLength(12.0); Box2.setBreadth(13.0); Box2.setHeight(10.0); volume = Box1.getVolume(); cout << "Volume of Box1 : " << volume <<endl; volume = Box2.getVolume(); cout << "Volume of Box2 : " << volume <<endl; Box3 = Box1 + Box2; volume = Box3.getVolume(); cout << "Volume of Box3 : " << volume <<endl; return 0;
