A tank is in the form of a cuboid with length 12 m. If 18 kilolitre of water is removed from it, the water level goes down by 30 cm. What is the width (in m) of the tank?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 5.
Volume of water = 18 kl = 18 cubic meter
length of cuboid = 12 m
Height = 30 cm = 0.3 m
Volume of water = length × width × Height
18 = 12 × 0.3 × width
width = 5 m
