Solution

The correct option is B False

If the square of a number is positive, then it is not necessary that the cube of that number will also be positive.

Let us understand with an example:

Considering -5

now, square of the -5 i.e. -52=25

Then, the cube of the same number i.e. -52=-125

Both are not equal.

Hence, the given statement is False.
