Question

The volume of water in a measuring jar is 24 mL. When a stone is immersed in the water, the water level rises to 32 mL. What is the volume of the stone ( in ${\text{cm}}^3$)?

• A. 8

Answer 1

The correct option is A 8
Initial water level on the jar = 24 mL

Water level after the stone is added = 32 mL

The water level rose due to the stone and the increase in the water level equals the volume of the stone.

i.e., Volume of the stone = Final water level - Initial water level
= 32 mL - 24 mL
= 8 mL

But, we know that $1\text{mL}=1{\text{cm}}^3.$
$\therefore$ The volume of the stone is $8\text{mL}=8{\text{cm}}^3.$
