Answer 2

The cube of double of "a" is $8a^{3}$.

Given,

The double of a.

To Find,

The cube of double of a.

Solution,

The method of finding the value of the cube of double of a is as follows -

We know that the double of a is 2a.

So, we need to find the value of $(2a)^{3}$.

We know by the rules of exponents $(ab)^{3}=a^{3}b^{3}$.

So, $(2a)^{3}=2^{3}*a^{3}=8a^{3}$

Hence, the cube of double of "a" is $8a^{3}$.
