Question 941554
capacity of te water tank  = length x width x hight
            = 4 x2 x 1.2
         = 96 m^3
but 1 m^3  =1000 liters
      = 96 *1000
 = 96000 liters
Capacity of tank  = 96000 liters
capacity of each bucket  = 15 liters
 no of buckets  needed to fill =  total capacity of water tank / capacity of each bucket
 = 96000/15
=6400
 Result :6400
