If the density of a 35.cm3 block of wood is .85 g./ml calculate the woods mass.
Reil [10]
So the equation you're going to be using is mass = density x volume 
So the volume of your block is 35cm^3, and your density is .85g/ml 

so your equation would be 

mass=.85g/ml x 35cm^3 

your final answer is 29.75g/cm^3

Hope this helps :)
