How many zoo animals does it take to fill up the biggest zoo in the world?

1.  Background Story:

How many Zoo animals (all land) does it take to fill up the biggest Zoo in the world with animals (in cages) and a place for people to walk, sit, play, and eat (inside and outside)?  I wanted to solve this question because I am interested in animals especially zoo animals and so that gave me the thought about all the different types of zoo animals and how many animals can fit in one zoo.

2.  Ask Yourself This:

1. What sizes are the cages? (Length and width)?

2. How many species?

3. What is the width of the path that the people can walk on?

(How big is a normal side walk?)

4. How big is the eating area, the store (where the food is) and the playing area.

( how big is a typical restraunt at a zoo in sq ft?)

5. How big is the biggest zoo in the world? (in acres)

6. How many animals per cage

7. How close are the cages to each other?

3.  Helpful Hints:  

a.  1. 750 acres http://www.therichest.com/rich-list/the-biggest/the-top-10-largest-zoos-in-the-world/  

2. 491 species http://www.therichest.com/rich-list/the-biggest/the-top-10-largest-zoos-in-the-world/

3. Normal sidewalk= 2 feet  (estimated)

4. restraunt= 900 sq ft 225ft/1side

5. cages= 6*5 meters  ( 19ft by 16 ft) 35 feet

6. Two-three animals per cage depending on how big the animals are. (Typically at every zoo I have gone to)

7. The cages are 10 ft away from each other but there is a walking space in between. (Estimated)

8. Playing area = 10ft*10ft (estimated)

b.  I found the width of a normal walkway and then I added it by 2.5 feet bacause I think the paved walkway should by wider for people to walk on.  I estimated the zoo walkway because there are all different sizes of them and so I added 2.5 feet onto a normal size of a sidewalk which was 2feet

normal sidewalk= 2 feet

Zoo walkway= 4.5 feet

2ft+2.5ft= 4.5 feet

4.  Construct a Formula:  

I can add the width of the sidewalk+ the length and width of the play area, the eating area,the store/shop,( all in feet) to find how much space there is for the cages . After I get that answer I find how many animals per cage and then multiplied that by how many cages there are,  will find that by subtracting the amount of sq ft everything else takes up from the amount a space a cage takes up,  and from there I can get that answer.

5.  Messy Math:  

1acre= 43,560sq ft.                                                               326,700,00Ft

32670000/1104.5 ft= 3267.0000Ft                                                      

750 acres= 32670000. Sqft     3267SqFt

4.5ft+100ft+ 100sqft+ 900sqft=1104.5 SqFt

Animals per cage= 2

3267.- 35 feet=3,232 feet

3,232/10 feet(between cages)=323 cages

323 cages*2 animals per cage= 646 animals

6.  Answer:  

2 animals per cage and 323 cages. 323 cages*2 animals per cage= 646 animals at the zoo.

323*2+646 animals at the zoo
