10.) The smallest division of a measuring cylinder is 1.0 ml Water is poured in it such that the water level reaches the 35 mark. When we put a stone into the water now the level reaches the 56 mark. What is the volume of the stone?
The smallest division of a measuring cylinder is 1.0 ml .
( 1.0 ml = 1 cm³ )
Water is poured in cylinder such that the water level reaches the 35 mark means 35 ml .
The volume of water is 35 cm³ .
After putting a stone into the water , now the level reaches the 56 mark means 56 ml .
Now the volume of water is 56 cm³ .
So , the volume of the stone is = ( 56 – 35 ) cm³ = 21 cm³ .
