Question

A 700 gm solid cube having an edge of length 10 cm float in water. How much volume of cube is outside the water. Use density of water 1000 $kg/m^3$

Answer 1

Volume of cube outside the water $=$ Volume of cube $-$ mass/density

$=(10{)}^{3}c{m}^3-\frac{0.7}{1000}$

$=1000-700=300c{m}^3$

Hence, this is the answer.
