Question

the water tank with length 4 m, breadth 1.5 m and height 1 m is completely filled with water. if it is to be emptied using a bucket of capacity 8 litres, find Ho many times the bucket should be used to empty the tank completely.

Answer 1

Length of water tank = 4m
Breadth """"""""""""""""= 1.5m
Height """"""""""""""""""=1m

Now,

Volume of tank = no. of buckets multiply volume of bucket
4*1.5*1 m^3= n*8l
6m^3 = n*8l
6000l = n*8l
n = 6000/8l
n= 750

Total no of bucket used is = 750

Answer 2

Answer:

750 times

Step-by-step explanation:

volume of tank = lbh

=4×1.5×1

=6m^2

m^2 to litres = 6×1000 ltr

=6000 ltr

no of times buckets used to empty the tank =

6000/8

=750
