math/chem question

The density of cobalt metal is 4.51 g/cm[SUP]3[/SUP]. Calculate the volume (in cm[SUP]3[/SUP]) of a piece of cobalt
weighing 8.32 g.

I know the answer but am not sure how many significant figures it would be. 1.84? or 1.8? haha it confuses me! like i know its 4.51g/1.??mL. ? being the amount of zeros.

In chem its usually 1.84 x 10 to the what ever power sig fig has to be between 1 and 9.99 if i remember correctly. Not sure i fully understand the question but this is what im reading at

I believe significant figures would be 2 after the decimal. They both have two so you can be accurate to 2. If one only had one then you could only be accurate to 1.
