If you want to find out the density of an object, what two things do you need to know about it?

How do I determine density? Density is not something that is directly measured. Typically if you want to know the density of something you will weigh it and then measure its volume.

your answer is c! hope this : )

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures
