43. A tank measures 0.6m by Im by 1.2m. 20 litres of water is poured into
the tank every 5 minutes. How long, in hours, will it take to completely
fill the tank if there were no breaks while filling the tank?​

Answer 1

Answer:

3 hours

Step-by-step explanation:

Volume of tank V = lbh

V = 1.2 × 1 × 0.6 = 0.72 m^3

1 m^3 = 1000 litres

0.72 m^3 = 720 litres

Number of fillings = 720 / 20 = 36

If 1 filling takes 5 minutes, then 36 will take

5 x 36 = 180 minutes = 180/60 = 3 hours
