Question

A cuboidal water tank of length 3 m, breadth 2 m and height 1.5 m is fully filled. After some time water height in the tank reduces by 0.5 m. Now, what is the amount of water present in the tank?

• A. 3000 litres
• B. 6000 litres
• C. 9000 litres
• D. 12000 litres

Answer 1

The correct option is B 6000 litres

Initially water is fully filled, therefore height of water in tank = height of tank
Height reduced = 0.5 m

Now the final height of water in tank
= 1.5 - 0.5 = 1 m

Volume of tank occupying water = 3 x 2 x 1 = 6 cubic metres

Since 1 cubic metre = 1000 litres

Amount of water present in tank
= 6 x 1000 = 6000 litres
