Each of the cubes measures 1 inch on a side.

The volume of the full stack of cubes is

cubic inches.

Imagine that each cube in the stack weighs 2 ounces. What would be the mass of the

whole stack of cubes?

ounces.

Imagine each cube weighs 3 ounces. What would be the mass of the whole stack?

ounces.

Imagine that each of the 1-inch cubes in the stack is made of copper, which is a kind of metal.

If the mass of 12 copper cubes measured together equals 60 ounces, what is the mass

of one copper cube?

ounces.

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.”
