Answer:
4698
Step-by-step explanation:
We know that 1 person is on 3quares, so we need to know how many squares value 3 has every room. We do that in the way- we calculate surface area of every room and divide with 3.
First room has surfaxe 75x75=5625
5625/3=1875
So the first room can have 1875 persons.
2nd room has surface 130x60=7800
7800/3=2600
The 2nd room can have 2600 persons.
3th room has 180 sets, so it is for 180 persons.
We also know that tey can add on every exit 10 more, and they have 4 exits, so it is
10x4=40
The total tickets they can sell is:
1875+2600+180+40=4695
