Question

when a solid is immersed in water standing to a height of 20cm in a vessel, the water level has raised 1/5 of its height. what is the percentage of increase in height? what is the percent height ?

Answer 1

Answer:

the percentage of increase in height is 20%

Step-by-step explanation:

The water rises by 1/5 of the height of the vessel.

So, the rise in water level is:

= 1/5 × 20 = 4 cm

The water goes up by 4 cm

Now, we need to get this as a percentage of the height of the vessel.

We do this as follows:

4/20 × 100 = 20%

The percentage increase in height is 20%.
