Question

If a number is doubled then which of

the following is a correct statement?
Select one:
A. Its cube is eight times the
cube of the given number.
B. Its cube is three times the
cube of the given number.
C. Its cube is two times the
cube of the given number.
D. Its cube is six times the
cube of the given number.​

Answer 1

Answer: Its cube is six times the

cube of the given number.

Explanation:

Let's assume we have a number which is 2. The cube will be:

= 2³

= 2 × 2 × 2

= 8

Let's now assume, we double the number 2, we'll have 2 × 2 = 4. Therefore, the cube will be:

= 4³

= 4 × 4 × 4

= 64

Therefore, from the explanation above, 2 raise to power 6 is 64. This means, if a number is doubled, then its cube is six times the cube of the given number.
