Marks: +1, -0

A cuboidal shaped water tank 2.1 m long and 1.5 m broad is half filled with water. If 630 litres more water is poured into that tank, the water level will rise

0.15 cm
0.18 cm
2 cm
0.20 metre

Solution:

Length = 2.1m breadth = 1.5m (given)
We know volume of the cuboid = Length x breadth x height
∴ Rise in water is given by,
Length x breadth x height = 630 litres (or)

630/1000m^3

2.1 x 1.5 x h =

630/1000 ⇒ h = ( 63/100 )(10/21 )(10/15 )

⇒ h = 0.2 m
Hence, option D is the correct answer.
