Answer 2

Given :- The number of children in town is also a perfect cube. If we give you a hint that this number is 864n.

To Find :-

• What is the smallest possible number of children in the town ?

Answer :-

Since the number 864*n is a perfect cube, its prime factors will be in pair of 3 .

so,

→ 864 = 2 * 2 * 2 * 2 * 2 * 3 * 3 * 3

→ 864 = (2 * 2 * 2) * 2 * 2 * (3 * 3 * 3)

as we can see that, 2 * 2 is not in pair of 3 . in order to make perfect cube , we have to multiply it by 2 .

then,

→ 864 * 2 = (2 * 2 * 2) * (2 * 2 * 2) * (3 * 3 * 3)

→ 1728 = (2 * 2 * 2) * (2 * 2 * 2) * (3 * 3 * 3)

therefore, smallest possible number of children in the town is 1728 .
