A fish tank is 40 cm long 60 cm wide and 50 cm height.it contains 50 litre of water.how many litre more water must be added to fill the tank to the brim
Answers
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.
70 litre of water must be added to fill the tank
Solution:
Given data:
Length of the tank = 40 cm
Width of the tank = 60 cm
Height of the tank = 50 cm
Volume of the tank = length × width × height
= 40 × 60 × 50
= 120000 cm³
Volume of the tank = 120000 cm³
Let us convert cm³ into litre.
1000 cm³ = 1 litre
120000 cm³ = 120000 ÷ 1000
= 120 litre
Total capacity of the tank = 120 litre
Tank already contains water = 50 litre
Quantity of water can added = Total capacity – Tank contains water
= 120 litre – 50 litre
= 70 litre
Hence 70 litre of water must be added to fill the tank.
