Answer 2

Answer:

A tank is in the form of a cuboid with length 12m. If 18 kilolitre of water is removed from it, the water level goes down by 40cm

Let width of the tank be w meters

We know volume of cuboid = length × width × height

Length = 12 m = 1200 cm.

Width = 100 × w = 100w cm.

Height = 40 cm^3

Thus, Volume of the removed water from tank

= 1200 × (100w) × 40 cm^3.

This volume is equal to 18 kiloliters of water

18 kiloliters = 18 × 1000 × 1000 cm^3

Accordingly

1200 × 100w × 40 cm^3 = 18 × 1000 × 1000 cm^3

4800000 w = 18000000

w= 18000000/4800000

w= 180/48

w = 15/4 meters

w = 3.75 meters

The width of the tank is 3.75 meters

Answer the width of the tank is 3.75 meters
