Solution:

1. Change 0.2 into fraction form.


0.2 = (2)/(10)

2. Simplify (2/10)³.


((2)/(10))^(3)


((2)/(10))((2)/(10))((2)/(10))


(8)/(1000)

3. Change 8/1000 into decimal form.


(8)/(1000) = (0.8)/(100) = (0.08)/(10) = (0.008)/(1) = 0.008

Thus, Option C is correct.

Explanation:

The exponent of a number describes how many times to multiply the number by itself.


(0.2)^3=0.2 * 0.2* 0.2

Multiply;


0.2 * 0.2 * 0.2


0.04 * 0.2


0.008


\boxed{C. \: 0.008 \: is \: the \: correct \: option.}
