If a number is doubled, then which of the following is a correct-state...
Explanation:
When a number is doubled, its new value becomes 2x, where x is the original value of the number.
To find the cube of a number, we multiply it by itself three times. So, the cube of the original number x is x^3.
Now, we can use this information to determine which statement is correct:
a) its cube is two times the cube of the given number
- This statement is incorrect because 2x^3 is not equal to two times x^3.
b) its cube is there times the cube of the given number
- This statement is also incorrect because 3x^3 is not equal to the cube of 2x.
c) its cube is six times the cube of the given number
- This statement is incorrect because 6x^3 is not equal to the cube of 2x.
d) its cube is eight times the cube of the given number.
- This statement is correct because (2x)^3 is equal to 8x^3.
Therefore, the correct statement is option 'D'.

8×8=64
64=64 [explained]
