The bells are adding a new room to their house . Volume of the room is 4096ft³. Let one side of the room is x We well know that The volume of the cube is x³ And x³=4096ft³ So , one side of the room x =√4096 x=16 ft And we have to find the area of the floor that becomes a square. Area of a square is x². If x=16 x²=16² x²=256ft² This is the area of floor of room. And the cost of hardware floor is 10$/ft² Now we have to find the total cost of hardware floor for room. Total Cost of floor = area of floor × cost /ft Total cost of floor= 256×10 Total cost of floor= 2560$.
