Question

can you measure how can you measure density of a piece of stone with the measuring cylinder and spring balance

Answer 1

You can find the wait the weight of stone with spring balance....and we know 
weight = mass x acc. due to gravity (g)
g= 9.8
density = mass / volume
you can find the volume with the help of measuring cylinder and mass = weight /9.8 
so u can find the density of stone....
hope it will help
