Question

In measuring the volume of a cork piece, initial water level in a measuring cylinder is kept at 50.2 ml. When a piece of iron is dipped into the water, the level reads 61.5 ml. When the same piece of iron tied to the given cork piece is dipped into the water, the level reads 68.1 ml. Find the volume (in cm${}^3$) of cork piece.

Answer 1

Volume of cork = volume of water with iron and cork - volume of water with iron

$V=68.1-61.5=6.6ml=6.6\times {10}^{-6}{m}^3$
