Answer:
The water in the tank filled to capacity lasts 20 days.
Step-by-step explanation:
Total number of students in the hostel = 300
The average need of water per day = 36,000 L
The dimensions of the tank = 10 m × 8 m × 9 m
Now, the capacity of the tank = LENGTH X WIGHT X HEIGHT
= 10 m × 8 m × 9 m = 720 cubic meters
Now, 
⇒
So, the capacity of the tank = 720,000 L
and the average usage of water by 300 students = 
⇒
or, number of days = 20
Hence, the water in the tank filled to capacity lasts 20 days.
Answer:
208 ft
Step-by-step explanation:
in order to do this we need to find the area of the retangle:
(l x w) 14x20= 280ft
then the area of the rectangle:
a^2 + b^2 = c^2 ( hypotenus lenght )
c= 8.5
now we can plug in to find the area of the triangle, which is 12 (11.99)
then the area of the trapezium= 60
finally we can find the answer
280 - (60+12)= 208 ft :)
