Question

the level of water in a measuring cylinder is 20.5 ml. When a stone is immersed in it the level of water becomes 30 ml. Find the volume of the stone in cm³.​

Answer 1

Answer:

Volume 1 = 20.5 ml

Volume 2 = 30 ml

volume = Volume 2 -Volume 1

= 30ml - 20.5 ml

= 9.5ml

1 ml = 1 cm^3

9.5 ml = 9.5 cm^3

Answer 2

Answer:

9.5 cm³

Explanation:

From the question :-

Change in volume of water = 30 ml - 20.5 ml

                                              = 9.5 ml

To find : volume of stone

Solution :-

By Archimedes principle :-

volume of the object = change in volume of water

volume of stone = 9.5 ml

volume of the stone = 9.5³ (∵ 1 ml = 1 cm³)

Hence, the volume of the stone is 9.5 cm³.
