2a. What is the density of a metal block with a volume of 15cm^3 and a mass of 5 grams show all work. 2b. Will that metal block float or sink? Why?

Explanation:

The density of a substance can be found by using the formula

So we have

We have the answer as

The block will float on water since it's density is less than that of water which is

1 g/cm³
