You have 1,000,000 number cubes, each measuring one inch on a side. If you stacked the cubes on top of one another to make an enormous tower, how high would they reach? Explain your reasoning.

Number of cubes = 1,000,000

Side of each cube = 1 inch

The cubes are stacked on top of each other to make a tower

Height of the tower = Number of cubes * Side of each cube

⇒ Height of the tower = 1,000,000 * 1

⇒ Height of the tower = 1,000,000 inches

Hence, the tower is 1,000,000 inches high
