List the property that must be present to call a rectangle a square.

when all the sides are equal in length

Step-by-step explanation:

if all the sides of a rectangle are equal in length,it is no longer a rectangle but a square

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

answer: its the third option.
