Calculate the density of an object using the following information: Mass = 50 grams and the initial water level is 30-ml in a graduated cylinder, but rose to 40-ml after the object was dropped into it.

The density of an object = 5 g/ml

Density is a quantity derived from the mass and volume  

Density is the ratio of mass per unit volume  

The unit of density can be expressed in g/cm³ or kg/m³  

Density formula:  

ρ = density  

m = mass  

v = volume  

Mass = 50 g

Volume of the object =

So the density :

aluminum

i guess but i think im right
