Question

The volume of liquid in a measuring jar is $200c{m}^3$. A cube of side $7cm$ is immersed in the liquid. What is the reading on the measuring jar?

• A. $543c{m}^3$
• B. $643c{m}^3$
• C. $843c{m}^3$
• D. $800c{m}^3$

Answer 1

The correct option is A $543c{m}^3$

Volume of liquid in a measuring jar $=200c{m}^3$
A cube of edge $7cm$ is immersed in the liquid,
Volume of cube $=7cm\times 7cm\times 7cm=343c{m}^3$
Reading on the measuring jar = voulme of liquid + volume of cube
$=200c{m}^3+343c{m}^3=543c{m}^3$
