Question

The cube of 0.4 is ____________

Answer 1

The cube of 0.4 is 0.064.

Step-by-step explanation:

• The cube of any number is defined to be the product of that number taken thrice.

• For example, a's cube = a³ = a × a × a.

• Numerical example: 7's cube = 7 × 7 × 7 = 49 × 7 = 343.

• In order to find the cube by hand, find the product of two numbers and then multiply the obtained value by that number one more time.

Here, the given number is 0.4

Its cube = 0.4³

= 0.4 × 0.4 × 0.4

= 0.16 × 0.4

= 0.064
