What does cube mean in math?

Answer 1

A geometric cube has three sides of equal length. A number cubed is multiplied by itself three times.

33 = 3*3*3 = 27

or

100x100x100=1,000,000

100x100=10,000

10,000x100=1,000,000

Answer 2

To cube a number means to raise it to the 3. So n cubed = n3 = n x n x n.

For example, 13 = 1 x 1 x 1 = 1

23 = 2 x 2 x 2 = 8

33 = 3 x 3 x 3 = 27

43 = 4 x 4 x 4 = 64

53 = 5 x 5 x 5 = 125
