you have 100.0mL graduated cylinder containing 50.0 mL of water. you drop a 124g piece of brass (density =8.56 g/cm^3) into water. to what height does the water rise in the graduated cylinder

mass = volume x density
124g = volume x 8.56
V = ?
The brass will displace its volume so the water will rise from 50.0 mL to 50.0+ V. 
so whats the V

we are looking for =cm^3

I substituted the numbers into mass = volume x density. All you need to do is to solve for volume (in mL which is the same as cc).

so now would i do this 124g/8.56 and whatever i get i add it to 50.0

Yes.
