Question: Write a program that calculates the volume and total surface area of a cube or cuboid. The program should ask the user to input the dimensions of the shape and should check if the shape is a cube or a cuboid. If the shape is a cube, the program should display the volume and total surface area of the cube. If the shape is a cuboid, the program should display the volume and total surface area of the cuboid.

int l,b,h;

int choice;

int area;

int volume;

public :

if(l==b && b==h )

{

cout<<"All side are same "<<endl;

choice=1;

area_calculte();

}

else

{

cout<<"All side are not same "<<endl;

choice=2;

area_calculte();

}

}

void area_calculte()

{

switch(choice)

{

case 1:

volume=l*b*h;

cout<<"volume of the cube"<<" "<<volume;

area=6*(l*l);

cout<<"Total surface area of cube"<<" "<<area;

break;

case 2:

volume=l*b*h;

cout<<"Volume of the cuboid is "<<" "<<volume<<endl;

area=2*((l*b)+(b*h)+(h*l));

cout<<"Total surface area of the cubodial"<<area;

break;

}

}

};

int main()

{

cin>>l>>b>>h;

// create object

calculte s1;

s1.cal(l,b,h);

return 0;
