A tank is in the form of a cuboid whose length is 20 metre. If 18 cubic metre water is removed from it the water level goes down by 15 centimetre. Find the width of the tank
Answers 2
Answer:
Volume of removed water = Length X width X decrease in water level
⇒ 18 = 20 X width X 0.15
∴ width = 6 metre

Given:
A tank is in the form of a cuboid whose length is 20 metres. If 18 cubic metres of water is removed from it the water level goes down by 15 centimetres.
To find:
The width of the tank.
Solution:
The width of the tank is 6m.
To answer this question, we will follow the following steps:
As given, we have,
The length of a tank which is in the form of cuboid = 20m
Now,
When 18 cubic metres of water is removed, the water level goes down by = 15cm = 0.15m (as 1m = 100cm)
Now,
We know that the volume of a cuboid is equal to the product of length, breadth and height of that cuboid.
Here,
The volume of removed water
= length × width × decreased height of water
So,
[tex]20 \times width \times 0.15 = 18[/tex]
[tex]3 \times width = 18[/tex]
[tex]width = 6m[/tex]
Hence, the width of the tank is 6m.

Answer:
1.Earth orbits the Sun at an average distance of 149.60 million km (92.96 million mi) in a counterclockwise pattern viewed above the northern hemisphere. One complete orbit takes 365.256 days (1 sidereal year), during which time Earth has traveled 940 million km (584 million mi).
2.Let m and M be the masses of the earth and the sun respectively and v the speed of the earth in circular orbit. To keep the earth in circular orbit, the gravitational force.
