What is the density of a block that has the dimensions of 2.5 cm, 3.2 cm, and 5.4 cm, and a mass of 6.38 g?
So we take the mass (in grams) and divide by the volume, which is the product of the linear dimensions:
Now even if I get the arithmetic wrong, I certainly have the right units for density. Would this block float on water? Why or why not?
