Abundantly 83354

If 10 mm of water fell on a trapezoid-shaped garden with bases of 30 m and 20 m and a height of 20 m, how many buckets of water would we need to water the garden equally abundantly if the bucket had a volume of 15 l?

Correct answer:

n =  333

Step-by-step explanation:

a=30 m c=20 m h=20 m  d=10 mm m=10:1000  m=0.01 m  S1=2a+c h=230+20 20=500 m2 V=S1 d=500 0.01=5 m3 V1=15 l  V2=V l=V 1000  l=5 1000  l=5000 l  n=V2/V1=5000/15=333
