[Question]Linda is building a new hotel with two wings. The first wing has 9 floors and each floor has 6 halls each with 32 rooms. The second wing has 7 floors each with 9 halls with 40 rooms each. How many rooms are in the hotel total?
[Answer]First find the number of rooms per floor in the first wing: 32 rooms / hall * 6 halls / floor = 192 rooms / floor. Then find the total number of rooms in the first wing by multiplying that number by the number of floors: 192 rooms / floor * 9 floors = 1728 rooms. Then find the number of rooms per floor in the second wing: 40 rooms / hall * 9 halls / floor = 360 rooms / floor. Then find the total number of rooms in the second wing by multiplying that number by the number of floors: 360 rooms / floor * 7 floors = 2520 rooms. Then add the total number of rooms in each wing to find the overall total: 1728 rooms + 2520 rooms = 4248 rooms. The answer is 4248.
