HURRY! ONLY 40 MINUTES
I have a cube 10 cm on a side. It floats in water with 40% of its volume above water. What is the density of the cube? Show your work.
Fraction of volume inside water = (100-60) =40%
Volume of cube =; = 1000
Volume of Displacement of water = 40% of 1000= 400
For floating,
Buoyant force = weight of cube
0.40
= 400
(Note: is density and for water 1 , g is acceleration due to gravity )
