A cube with a side 1 m long has been cut into cubes of a side 1 dm each. all small cubes have been put one on top of the other, to form a vertical structure. what is the height of this structure?

First, we have to find how many small cubes formed by the large cube.

To find the number of small cubes, we should calculate the volume of each large cube and small cube. Equalize the volume units to dm³

Dimension of large cube

s = 1 m

s = 10 dm

Volume of large cube

v = s³

v = 10³

v = 1,000 dm³

Dimension of small cube

s = 1 dm

Volume of small cube

v = s³

v = 1³

v = 1 dm³

Second, calculate the number of small cubes formed

n = volume of large cube / volume of small cube

n = 1,000 dm³ / 1 dm³

n = 1,000

There are 1,000 small cubes.

Third, calculate the height of the structure.

The structure is formed by 1,000 cubes. Each of them is 1 dm high.

The height of the structure is

h = 1 dm * 1,000

h = 1,000 dm

h = 100 m

The height of the structure is 1,000 dm or 100 m
