Ahallway measuring 90 feet x 7 feet requires 1/2 a fluid ounce of cleaning solution per square foot. how much cleaning solution is required to clean the hallway?

Think of it as a very long and wide but thin box. First find the area.. So 90 x 7. Then multiply that product by your .5 (1/2) That way, for every square foot, you are giving it the 1/2 a fluid ounce of cleaning solution! If you want to, you could just think of it as finding the volume. (L x W x H.) Good luck!
