Question

A metallic piece displaces water of volume 15 𝑚𝑙. The volume of piece is :

• A. 15 $m^3$
• B. 15 $c{m}^3$
• C. 15 $\times {10}^{3}c{m}^3$
• D. 15 $\times {10}^{3}c{m}^{-3}$

Answer 1

The correct option is B 15 $c{m}^3$

Each body occupies space equal to its own volume.
Therefore, if a metallic piece is immersed in a liquid, it displaces the volume of liquid equal to its own volume so as to occupy the space of liquid.
Thus, Volume of metallic piece = Volume of liquid displaced by body when completely immersed in liquid =15 𝑚𝑙=15 $c{m}^3$
$1ml=1c{m}^3$
Hence option (i) is correct.
