Q. When a toy of irregular shape is immersed in a measuring cylinder containing water of $20ml$, the water rises to $37ml$, then the volume of the toy is:

1. $20\times$${10}^{-6}$$m^3$
2. $17\times$${10}^{-6}$$m^3$
3. $37\times$${10}^{-6}$$m^3$
4. $27\times$${10}^{-6}$$m^3$

Q. The initial level of water in a measuring cylinder was $12\text{ml}$. When an iron piece of irregular shape is completely immersed, the water level increased to $30\text{ml}$. What is the volume of the iron piece?

1. $18\times {10}^{-3}{\text{m}}^3$
2. $18\times {10}^{-6}{\text{m}}^3$
3. $18\times {10}^{-6}{\text{cm}}^3$
4. $18\times {10}^{-4}{\text{m}}^3$

Q. Bottom of a regular water tank has an area of $8m^2$. The volume of the tank is $16m^3$. What is the height of the tank?

1. $1m$
2. $2m$
3. $3m$
4. $4m$
