Question

68.A fish tank has length 40 cm, breadth
60 cm and height 50 cm. It contain 50 litre
of water. How many litre of more water
will be needed to completely fill the tank?
1. 50 litre
2. 60 litre
3. 70 litre
4. 120 litre​

Answer 1

Answer:

Find the capacity of the tank:

Volume = Length x Breadth x Height

Volume = 40 x 60 x 50 = 120000 cm³

Convert the cm³ to ml:

120000 cm³ = 120000 ml

Convert the ml to litres:

120000 ml = 120 litres

Find the amount of water needed to fill the tank to the brim:

Amount of water needed = 120 - 50 = 70 litres

Answer: 70 litres of water is needed to fill the tank to the brim.
