Maybe you understood that if the individual cubes weigh 5 ounces each, then the full stack of 12 cubic inches would weigh 60 ounces.

Or you could divide the mass of the full stack (60 ounces) by the number of cubes (12) to get 5 ounces per 1 cube.

​

​There are different ways to figure out the mass of one copper cube.

​Per means “for every.”

Using American measurements, a 1-inch cube of copper weighs 5 ounces, so copper has a density of 5 ounces per cubic inch.

​

The mass of one cube is

the same as the density

of the substance.

​Per means “for every.”

​Think ABOUT it.
